Good evening and welcome to Sports Mole's live coverage from day four of the athletics at the Olympic Games in London.
Tonight is all about medals - five of them! Golds will be won in both the women's pole vault and shot put, as well as the men's 400m and hurdles over the same distance.
The women steeplechasers will also be competing for the big prizes.
All of that means that the likes of Dai Greene, Holly Bleasdale and Perri Shakes-Drayton will all representing Team GB over the course of the evening.
We'll have EVERYTHING covered right here.
10.10pmRight, that's it from us tonight! Make sure you join Sports Mole again tomorrow for live commentary on all the day's actions. Thanks for reading, and good night!
10.09pmThen, in the evening, we have medals to be decided in the men's high jump, discus and 1500m, while the women will be competing for gold in the 100m hurdles.
10.07pmThe morning sees action in the men's 110m hurdles, triple jump and 200m, while the women are in action in the javelin and 5000m.
10.07pmThe morning sees action in the men's 110m hurdles, triple jump and 200m, while the women are in action in the javelin and 5000m.
10.06pmI couldn't leave you with bad news, though, so here's a preview of what you can look forward to tomorrow...
10.03pmJust a small bit of bad news towards the end of the night, however, as Denisa Rosolova has won her appeal against her disqualification in the women's 400m hurdles, which means that Team GB's Perri Shakes-Drayton has lost her place in the final.
10.01pmThen, finally, the women's pole vault was decided as Jennifer Suhr took gold ahead of Cuba's Yarisley Silva. Pole vaulting legend Yelena Isinbayeva could only manage bronze, while GB's Holly Bleasdale tied for sixth place.
9.59pmIn the night's showpiece event, Grenada's Kirani James cruised to gold in the men's 400m final, while Luguelin Santos and Lalonde Gordon came second and third respectively.
9.57pmRussia's Yuliya Zaripova won the women's 3000m steeplechase with the third fastest time in history, beating Habiba Ghribi of Tunisia and Sofia Assefa in the process.
9.54pmBritain's biggest hope of a medal tonight lay in the hands of Dai Greene in the men's 400m hurdles final, but he could only come fourth as an emotional Felix Sanchez took gold. Michael Tinsley and Javier Culson picked up silver and bronze respectively.
9.52pmIn the women's 400m semi-finals, Perri Shakes-Drayton qualified by the skin of her teeth after the previous fastest loser was disqualified, but there was no such luck for Eilidh Child, who was eliminated.
9.49pmTwo Brits progressed to the semi-finals of the women's 200m, namely Abiodun Oyepitan and Margaret Adeoye. Favourites Carmelita Jeter, Veronica Campbell-Brown, Allyson Felix, Murielle Ahoure and Sanya Richards-Ross also qualified.
9.44pmNadzeya Ostapchuk of Belarus won gold in the women's shot put, beating defending Olympic champion Valerie Adams of New Zealand. Russia's Evgeniia Kolodko picked up bronze.
9.43pmSo, let's take a look back at some of tonight's action shall we? I think a round-up is in order.
9.41pmGOLD MEDAL! Silva can't do it and Jennifer Suhr clinches the gold!
9.40pmWe're approaching the end of the women's pole vault too, with just Cuba's Silva yet to jump. If she gets over the 4.80m barrier then she wins gold. If not then Suhr will get it, simple as that.
9.38pmKevin Borlee won the family battle against his brother Jonathan for anyone who is interested. They finished fifth and sixth respectively.
9.36pmMichael Johnson has just backed James to be the man who could challenge his long-standing 400m world record, that's how highly this man is rated. Certainly one to watch over the next few years.
9.35pmJames's time was 43.94, the first sub 44 second 400m run of his life, and what a time to produce it!
9.33pmDominican Republic's Luguelin Santos picks up the silver and Lalonde Gordon takes the bronze. Chris Brown of the Bahamas once again finishes fourth.
9.32pmGOLD MEDAL! Kirani James wins it, and in some style! The teenager finished quite a way ahead of the rest of the pack, very impressive and a personal best.
9.31pmAlso, in lanes 1 and 8 are the Borlee twins from Belgium, the first time there have been twins in an Olympic final.
9.30pmKirani James is the world champion going into this one, and will be looking to get Granada their first EVER Olympic medal.
9.28pmLet's turn our focus to the showpiece event of the night - the men's 400m final. Some good, young talent here and quite an open field. The first time there have been no Americans in the 400m final.
9.27pm...and she's failed! Isinbayeva, winner of the last two Olympic women's pole vault titles will have to settle for bronze, while it's between Suhr and Silva for gold now.
9.26pmBack to the pole vault once more then! Isinbayeva with her final attempt...
9.25pmHabiba Ghribi's silver in the steeplechase, I've just been informed, was Tunisia's first ever medal in athletics, so well done to her!
9.24pmFelix Sanchez is in bits as he goes up to accept his 400m hurdles gold medal. Great to see such passion.
9.19pmSuhr fails on 4.80, but Isinbayeva, the greatest woman pole vaulter ever and a two-time Olympic champion will just have one attempt to clear that height. Could she be on her way out?
9.18pmBack to the pole vault now...
9.16pmThat was the third fastest steeplechase of all time from Zaripova (9:06.72). Tunisia's Habiba Ghribi picks up the silver and Ethiopia's Sofia Assefa
9.14pmGOLD MEDAL! She's done it! Yuliya Zaripova has added the Olympic title to her world title after leading from start to finish. Fantastic final 400m from the Russian.
9.13pmRussia's Zaripova leads.
9.12pmSurprise in the steeplechase, meanwhile, as defending champion Galkina walks dejectively off the track. We're into the final lap.
9.10pmCuba's Silva is over too! The bar has been raised in this contest, no pun intended. Honest.
9.08pmWe have our first clearance of 4.75m in the pole vault, and it has come for Suhr! Isinbayeva failed in her first attempt, so the pressure is on the Russian now.
9.06pmAll the competitors get safely over the water hurdle.
9.04pmKenya will be looking for a male and female 3000m steeplechase double, and Milcah Chemos Cheywa is more than capable of providing it. She'll face stiff competition from Olympic champion Gulnara Gulkina, though.
9.01pmTeam USA's Jennifer Suhr currently leads the pole vault final, closely followed by Yelena Isinbayeva and Yarisley Silva, all of whom have cleared 1.70m. Isinbayeva, a legend in the sport, is looking in imperious form though.
8.59pmStill more medals to be decided tonight, and next up is the women's 3000m steeplechase final.
8.55pmDai Greene tells BBC Sport: "I felt a bit tired tonight but I gave it everything I had."
8.53pmSanchez's winning time tonight was exactly the same as his winning time in Athens eight years ago.
8.50pmMichael Tinsley ran a personal best to win silver, while Javier Culson claimed bronze, Puerto Rico's first ever track and field medal.
8.48pmActually, replays show that Greene just nipped into fourth at the end, but that will be scant consolation for the Welshman.
8.47pmGOLD MEDAL! Felix Sanchez takes the gold! Eight years after his last gold, Sanchez runs a 47.63 to win another. GB's Dai Greene, however, can only manage fifth despite a valiant effort in the final straight.
8.46pmBut he's fallen very far behind!
8.46pm...and we're off! Good start from Greene!
8.45pmHere we go...
8.44pmJavier Culson is probably favourite here, having not lost in this event all year, but Felix Sanchez is the fastest man in the final, so this could be very interesting!
8.43pmOK, we're now just a couple of minutes away from Dai Greene's 400m hurdles final. Greene qualified here by the skin of his teeth, despite being one of the favourites, and will have to run a lot better this time around.
8.40pmSome news from the 400m hurdles, and it is good news for GB! The woman who knocked Shakes-Drayton out of the fastest loser spot, Rosolova, has been disqualified, which means that Shakes-Drayton WILL be in the final.
8.38pmBolt jumps onto the podium to a massive cheer. The man transcends his sport, and sport in general, as well as nationalistic tendancies. No matter where you're from, you just seem to want this man to win, and he never disappoints on the biggest stage.
8.37pmA word to for Bolt's teammate and friend Yohan Blake, who pushed Bolt all the way and was very gracious in defeat.
8.35pmHere comes the medal ceremony for the men's 100m, the Olympics' showcase event. We all know who stands atop the podium. The greatest sprinter of all time? Perhaps even the greatest athlete of all time? Usain Bolt, take a bow.
8.34pmUSA's Georganne Moline finishes second, but it's a double blow for Team GB as Shakes-Drayton misses out on a fastest loser spot.
8.32pmChild starts to fall behind going into the home straight and is not in sight as Odumosu wins the heat.
8.32pmNot to mention Shakes-Drayton still in the fastest loser spot.
8.31pmOnce again we have British interest in the 400m hurdles, this time Scotland's Eilidh Child.
8.29pmCuba's Yarisley Silva and Germany's Silke Spiegelburg lead the pole vault, meanwhile, with a leap of 4.65m.
8.28pmPerri Shakes-Drayton tells BBC Sport: "I was running blind with the faster girls inside me. We'll just have to wait and see I guess."
8.26pmShakes-Drayton's time could still be enough to give her a place in the final though. 55.19 is her time, if no-one who finishes outside the top two goes faster in the next race then she's in the final.
8.24pm...but she can only manage third place as USA's Lashinda Demus and Jamaica's Kaliese Spencer finish some way ahead of the rest.
8.24pmShakes-Drayton has got off to a good start...
8.23pmRight let's get back to the hurdles, and Team GB's Perri Shakes-Drayton is up in the next race.
8.20pmGOLD MEDAL! The women's shot put, meanwhile, has come to it's conclusion and it's gold for Nadzeya Ostapchuk of Belarus. Dominant display from her over a very talented field.
8.19pmOh so close! Bleasdale is almost over the 4.55m mark on her final attempt but just clips the bar on the way over. Heartbreaking for the Brit, who is in tears.
8.18pmBack to the pole vault and here comes Bleasdale. She needs a good one here.
8.17pm...and sure enough she cruises to a comfortable win with a time of 53.3, while Zuzana Hejnova comes second. We have our first two finalists!
8.17pmAntyukh is looking very good here...
8.15pmOnly the top two will automatically progress to the final from this race, so a lot to play for.
8.14pmThis race includes world number one, Russia's Natalya Antyukh.
8.13pmWe'll shift our focus now to the first semi-final of the women's 400m hurdles, which is about to get underway.
8.12pmAnother disappointing effort from Bleasdale as she gets her stride all wrong. She looks frustrated to say the least.
8.11pmNow she comes...
8.10pm...maybe not just yet, a short delay while the national anthem of Kenya rings around the stadium for last night's 3000m steeplechase winner, Ezekiel Kemboi.
8.09pmHolly Bleasdale is about to take her next effort...
8.08pmThanks Liam, let's get straight back into the action with the women's pole vault.
8.07pmAnd that is as far as I take you. Mr Corkhill will guide you through the remainder of the evening, starting with the women's 400m hurdles semi-finals. Enjoy.
8.03pmBad news for the Brits after the final heat as Onuora fails to qualify as a fastest loser.
8.02pmAnthonique Strachan came second, while Elyzaveta Bryzgina finished in the final qualifying slot.
8.01pmHow easy was that for Shelly-Ann Fraser-Pryce? Very, is the answer! She wins through in a time of 22.71 seconds.
8.00pmBack over to the track and the final women's 200m heat.
8.00pmHere goes Bleasdale in the vault at 4.55m...and she fails at the first attempt.
7.57pmQuickly over to the women's shot put and defending champion Valerie Adams is on the verge of losing her crown. She has just one more throw remaining.
7.55pmCampbell-Brown spoke with BBC Sport after her race: "The objectivity is always to advance to the next round and I did that, so it's good. It's a great situation to be in. I'm taking it step by step."
7.54pmUkraine's Mariya Ryemyen won the race 22.58.
7.53pmBut the Jamaican can only qualify in third place. She looked smooth, but by no means quick. Will need to improve in the semi-finals.
7.50pmPenultimate women's 200m heat coming up. Veronica Campbell-Brown is competing in this one.
7.49pmBack to Richards-Ross, who has been talking to BBC Sport: "I didn't get to bed until two in the morning. But I'm excited and I'm on a mission. It's an event that I can run freely."
7.47pmYES! She's done it! What relief. The noise in the Olympic Stadium when she cleared that was incredible. Right, the medal charge begins for the youngster.
7.46pmBack to the vault. Bleasdale's final attempt at 4.45m. It's now or never...
7.45pmWell that was rather easy for Richards-Ross. Despite easing up around the bend, the American stepped on the gas down the home straight to win the heat and clock a time of 22.48 seconds.
7.43pmHeat four of the women's 200m up next and her comes 400m Olympic champion Richards-Ross.
7.39pmAn analytical Oyepitan talking to BBC Sport: "I eased up a bit. It was okay. I didn't drive long, it was very, very short. I need to drive long and hard. That's something I need to work on for the semi-final."
7.38pmThe final qualifying slot went to Sherone Simpson of Jamaica.
7.37pmJeter wins it in 22.66 seconds, with Oyepitan impressing greatly in second spot. She's got a real chance of reaching the final here.
7.36pmHeat three of the women's 300m coming up. Britain's Abiodun Oyepitan goes, as does America's Carmela Jeter.
7.35pm...But it's another fail. She got over the bar fine, but clipped it on her way down. In all honesty, this is a modest height. One more attempt to go. She's out unless she clears it.
7.34pmBack at the vault, second attempt at 4.45m for Bleasdale...
7.33pmShe has since spoken to BBC Sport: "The race was good and the crowd lifted me. I tightened up towards the end. All in all I really enjoyed being at the Olympics. Hopefully I will get the chance to compete again. Fingers crossed." Her time by the way was 23.23 seconds.
7.31pmNot such good news for fellow Brit Anyika Onuora, who finished fourth in the second heat. She must now wait to see if she is a fastest loser. Fingers crossed!
7.30pmAdeoye tells BBC Sport: "I didn't want to disappoint the crowd. I thought I've got to execute it from them at least."
7.28pmAnd in the first heat Britain's Margaret Adeoye has qualified for the semi-finals. Great run from the sprinter, who clocked a personal best time of 22.94 seconds.
7.24pmComing up shortly is the heats of the women's 200m, which we'll soon turn our attention to. Sanya Richards-Ross, who won gold in the 400m last night, is back in action.
7.19pmNo! She knocks the bar clean off with her feet. Poor technique from the youngster.
7.18pmHere comes to Brit. Can she clear 4.45m?
7.16pmBoyd also knocks the bar off with her hands has she attempts 4.45m. A lot of the competitors are registering fouls at the moment. Got to be good news for Bleasdale.
7.15pmGermany's Martina Strutz also fails, hitting the bar with her thighs.
7.13pmNo such joy for Poland's Anna Rogowska, who clips the bar on her way down.
7.11pmBack to the vault, Vanessa Boslak and Becky Holliday both clear 4.30m.
7.10pmLooking ahead to Dai Greene's final, former British javelin thrower Steve Backley tells BBC Sport: "I think the challenge for Dai is that in qualification he was in the outside lane and ran blind. I think he got a bit of a fright and might just admit to himself he got in a panic. The key now is it's all in front of him this time and something feels really good about that."
7.08pmThe early stages of the vault sees Jirina Ptacnikova from the Czech Republic clear 4.30m. Bleasdale is due to go seventh.
6.59pmSo, the finals of the women's shot put and pole vault are coming up in a few minutes. We'll be keeping a close on Team GB's Holly Bleasdale in the vault, while keeping you updated with the shot put.
6.50pmAlso look out for Perri Shakes-Drayton in the women's 400m semi-finals. She ran extremely well in the heat and will be looking to do the same tonight.
6.48pmSo, where is Britain's best medal chance this evening? Tricky one. My tip is going to be Dai Greene. Granted he ran extremely poorly during the semi-finals, but he goes in lane three this time. If his head is in the right place, he can claim a medal.
6.44pmThe women's steeplechase follows, before the night is ended with the men's 400m final. You lucky, lucky people!
6.42pmIt's then the turn of the men at around 8.45pm in the final of the 400m hurdles.
6.40pmMore women events follow as the heats of the 200m and the semi-final of the 400m hurdles get underway.
6.37pmThe women go first in the shot put and pole vault at around 7pm. Britain's Holly Bleasdale will be going in the latter of those events.
6.36pmEvening all! Just the five medals on offer tonight, will that do for you?!
12.57So, Sports Mole's coverage of the athletics is done for now but don't fear, we will be back 6.30pm to take you through all of the evening's action. Thank you for joining us and make sure you come back later!
12.54If that wasn't enough, the women's 200m heats and women's 400m hurdles semi-finals will also be gracing the Olympic Stadium tonight.
12.53The women's 3000, steeplechase final and the men's 400m final is due to get underway this evening.
12.52We also have GB's Dai Greene contesting for a medal in the 400m hurdles final. If you remember, the Welshman just edged into the final after finishing as the fastest loser, so this could be a tense contest tonight!
12.51There are medals to be won tonight in the women's shot put and women's pole vault final.
12.50So that's all the track and field action from this morning! However, there's plenty to look forward to as the athletes return to the stadium for this evening's events.
12.47Andrew Osagie was just one out of three Brits who could manage to reach the semi-finals of the men's 800m, while Hannah England, Lisa Dobriskey and Laura Weightman secured spots in the 1500m semi-finals after qualifying from their respective heats.
12.45Belarus's Ostapchuk and New Zealand's Adams launched themselves into the final of the women's shot put with a decent 20.76m and 20.40m respective throws.
12.43There is also a British contingent in the 100m hurdles with Tiffany Porter, who will line up in lane 8 in tomorrow's second semi-final.
12.42The women's 100m hurdles semi-finals have been decided, with Olympic favourite Sally Pearson expected to get on the podium after an impressive heat from the Australian.
12.40Let's have a recap of what we've witnessed this morning at the Olympic Stadium shall we?
12.37So the men's qualifiers for the discus are over and Great Britain have a shot at another medal with 20-year-old Okoye.
12.35He does do better as he reaches 63.09m but it's not enough to secure a place in tomorrow's event.
12.34Rutger Smith of the Netherlands is up on the circle now trying to better his 62.70 throw for a place in the final.
12.32Britain's third representative in the discus Brett Morse missed out on a spot in the final after throwing 58.18m, which was his best of the day.
12.29Okoye has reached the final! He throws a 65.28m to contest for a gold medal tomorrow. It's the fourth furthest throw seen today after his horror start.
12.29And he's done it! The crowd erupts as Okoye blasts well past the 65m mark.
12.28The 20-year-old has stepped up to the circle and the crowd are willing him on!
12.27GB's Abdul Buhari will not make the final after he threw his best discus of 60.08m. However, Lawrence Okoye still has a chance of making it after throwing a foul shot in his first attempt.
12.25Right, let's now turn our attentions to the men's discus throw qualifiers. Kanter, Harting, Fernandez, Gowda and Hadidi have already qualified for tomorrow's final.
12.21So, good news for the Brits as all three women reach the semi-finals of the 1500m.
12.18Right, so here are the first six to qualify in the third heat for the 1500m semi-finals: Bulut, Uceny, Kareiva, Kotstetskaya, Belete, Weightman.
12.17But she's done it! The Brit grabs the sixth qualifying place after a quick sprint down the home stretch.
12.16Kipyegon looks like she's struggling slightly and Weightman tries to come to the front from the outside.
12.16Kipyegon has upped the pace here but Dibaba stays on her heels.
12.14Kenya's Kipyegon just edges to the front, while Weightman tucks herself into the pack but will want to move up as the group prepare to enter the final lap.
12.13And they're underway with Dibaba taking the lead and Weightman sitting at the back with the race steadying into a rather slow pace.
12.12The Brit will be hoping to join her compatriots Hannah England and Lisa Dobriskey in the semi-finals.
12.12A huge roar from the crowd rings around the Olympic Stadium as Laura's name is read out first ahead of the heat.
12.10We have another British athlete on the track, ready and raring to go! Laura Weightman begins her campaign in the third and final heat.
12.09We have some quotes from Hannah England following her fifth-place finish in heat one of the 1500m. The 25-year-old told the BBC: "I'm so, so happy and very relieved. Making the semi-final was about all the cross-training and the coaching. I can't believe I managed to run like that and it will set me up for the next round."
12.07So, the six automatic qualifiers are: Dobriskey, Hilali, Cakir Alptekin, Fernandez, McKnight, Simpson.
12.06Scratch that, Lisa Dobriskey actually finished first with a time of 4:13.32s. An impressive and confident start to her Olympics campaign.
12.05With 200m to go Dobriskey moves up into the shoulder and launches into the final stretch clinching the second qualifying spot after a positive run.
12.04Dobriskey is moving to the front slightly but she is boxed into the inside lane as the bell sounds for the final lap.
12.03Hilali of Morocco currently sits in second place, with GB's Dobriskey in around eighth as the group settle at a steady pace.
12.02Dobriskey tucks herself into the middle of the group with Spain's Fernandez taking the lead.
12.01Back to the second heat of the women's 1500m though. And off they go!
11.59Oh dear, Lawrence Okoye has just fluffed his first throw in the discus. He has two more chances to get it right but the teen will need to calm his nerves before stepping back up to the circle.
11.58Lisa Dobriskey is the second Great Britain representative in the 1500m, which is due to get underway any moment.
11.57Aregawi, Tomashova, Jamal, Obiri, England and Stellingwerff complete the first six automatically into the semi-finals of the 1500m.
11.55Ethiopia's Aregawi finished in front, with Tomashova clinching the second qualifying spot after leading for the majority of the race.
11.54Seems as though England's tactics worked as she passes the finish line in fifth place.
11.53England slides nearer to the front as the bell goes for the final lap but Tomashova continues to stay in front.
11.52England is quite comfortable so far as she tucks herself into the group and currently sits in fourth. Keep in mind that the first six qualify automatically.
11.51Tomashova, who has been found guilty of doping in the past, moves to the front over the Brit to pick up the pace.
11.50And they're off! The crowd are well behind England in these early stages as she strides to the front of the pack.
11.48The 25-year-old will have Britain's hopes on her shoulders but the Oxford-born athlete has struggled with injury leading up to the London Games.
11.46So, the 800m are done but we have the women's 1500m heats due up in four minutes or so! Great Britain have Hannah England, who won silver at the World Championships last year, in the first heat.
11.43So, Great Britain have just one athlete in the semi-finals of the 800m with Andrew Osagie.
11.41So, let's look at their times. USA's Solomon - 1:46.05. Netherlands Olivier - 1:46.06. South Africa's Olivier - 1:46.42.
11.40Lathouwers for the Netherlands finished in second with South Africa's Olivier nabbing the third spot.
11.39Or not! Solomon eases past the finish line and looked very comfortable, despite taking the lead instantly.
11.39This is one of the quickest heats as we enter the final lap. Solomon's taken a considerable lead here but the others should start to test the American here.
11.38And here they go! As we thought, Solomon has started off quickly and already takes the lead as they reach the first bend.
11.36Right, back to the 800m heats. Number seven is due to get going any moment, with Duane Solomon for the USA expected to do well here.
11.35Let's just switch to the women's shot put for a moment. Nadzeya Ostapchuk for Belarus and New Zealand's Valerie Adams are well ahead of their competitors at the moment with throws of 20.76m and 20.40m respectively.
11.33Here's the confirmed times for you! Ethopia's Aman - 1:47.34. Kenya's Chemut - 1:47.42. Spain's Reina - 1:47.44.
11.31Chemut managed to keep his pace but Aman just crossed the finish line before him, with Reina taking the third qualifying spot.
11.31As we enter the final lap, Chemut is still leading but the pack are breathing down his neck.
11.3018-year-old Chemut charges into the lead in the early stages. Just what we expected from the Kenyan.
11.29Heat six have just got underway!
11.27Here's the times for heat five then: Egypt's Mohamed - 1:48.05. Iran's Moradi - 1:48.23. Spain's Lopez - 1:48.27.
11.25Egypt's Mohamed crossed the finish line first, with Moradi and Lopez clinching the final two spots.
11.24It seems as though Rimmer went too early. The Brit failed to maintain his lead and it looks as though he won't qualify for the semi-finals.
11.23The crowd are roaring as Rimmer takes a strong lead but Mohamed overtakes him for the home stretch.
11.22Rimmer has taken the lead around the first bend of the track, with Cortez and Camara sitting behind.
11.22And they're off!
11.20Great Britain have another representative in Michael Rimmer for the fifth heat of the 800m. He starts in lane 9.
11.18So here are the qualifiers: USA's Symmonds - 1:45.91. Canada's Harris - 1:45.97. Poland's Kszczot - 1:45.99.
11.16Former Olympic champion, Russia's Borzakofsky led from the start of the final lap but slipped back towards the last 100m and will have to discover his fate after the final heat of the day.
11.15Symmonds dropped back slightly but managed to launch himself to the front on the home stretch to clinch the quickest time of the heat.
11.14And here we go! Nick Symmonds of the USA has started off the quickest here as the athletes join together on the inside lane.
11.12Right, heat four of the 800m are almost ready to get underway.
11.10Warburton's time of 1:46.97 will not be enough for the Brit to join his compatriot Andrew Osagie into the semi-finals.
11.09Heat three qualifiers: Sudan's Kaki - 1:45.51. Kenya's Kitum - 1:45.72. Saudi Arabia's Mohammed - 1:46.09.
11.08Unfortunately for Warburton, the Brit comes in fifth but it was expected to be a tough test for the Welshman.
11.07Warburton needs to launch himself as they come into the home straight but Kaki is still controlling.
11.0717-year-old Kitum finds himself in third after coming up from the back and could clinch a spot in the semis here.
11.06Warburton has started off well as Kaki leads the pack early as they reach the first bend.
11.06And we're off!
11.04This won't be easy for this member of Team GB. It's worth keeping your eyes on Kenyan youngster Timothy Kitum.
11.03Right, we have another Brit up in heat three with Gareth Warburton starting in lane 2.
11.01So here are the first qualifiers for heat two of the 800m. Kenya's Rudisha - 1:45.90. Qatar's Balla - 1:46.37. GB's Osagie - 1:46.42
11.00Rudisha grabs the first qualifying time with ease after striding to the finish line.
10.59Osagie blasts near to the leading men in the final stretch and we think he has just clinched third.
10.59And the bell goes for the final lap. Osagie is fifth at the moment with Rudisha leading at the front.
10.58Osagie started off quickly out of the blocks and comfortably sits in the middle of the pack as they reach the first bend.
10.56Hello all! Hope you're enjoying our coverage so far. Now, let's keep our fingers crossed for Brit Osagie, who has just received a rapture of applause from the crowd as his name is called out.
10.55amAnd that is as far as I take you. Danielle will guide you through to 1pm, starting with the second heat of the men's 800m, which includes Britain's Andrew Osagie. Enjoy!
10.54amQuick switch to the cage, where Morse has fouled again. He won't get through now. His Olympics is over I'm afraid.
10.53amBrazil's finished second in Fabiano Pecanha, with Mohammad Al-Azemi from Kuwait coming third.
10.52amYouth World Champion Nijel Amos wins it in a time of 1.45.
10.50amSeven heats of the men's 800m coming up. Here comes the first...
10.47amIndia's Vikas Gowda has joined Hadadi in making the qualifying distance. He actually went slightly better than his rival, throwing 65.20m. These two are still the only ones to have reached the required target.
10.45amComing up shortly we have women's shot put and men's 800m. But before that, let's give you a quick update on the men's discus.
10.44amThe concludes the heats for the women's 100m hurdles. The semi-finals will take place tomorrow.
10.43amCanada's Phylicia George also gets through, as does Marzia Caravelli.
10.41amIt's easy for Jones, who clocks a time of 12.68.
10.41amNext up on the track is America's Lolo Jones. Final heat.
10.39amBREAKING ATHLETICS NEWS: GB's Phillips Idowu arrives at the Olympic Village and will compete in the triple jump tomorrow. Story developing here.
10.37amPearson has been speaking to BBC Sport: "I was really nervous for that race and I'm glad it is out the way. There's no more work to do, this is it. I'm just taking it one race at a time and see what I can do."
10.36amFrance's Reina-Flor Okori came second, with Carolin Nytra in third.
10.34am12.58 is the answer! That is stunning from Pearson in the qualifying round. A big message sent out to her rivals.
10.31amBack over to the track and here comes Pearson. How will she deal with the pressure of being the overwhelming favourite to take gold?
10.30am...and it is. 58.18m. Needs more, much more!
10.30amOver to the discus and Morse again. He throws it cleanly this time, but it looks short...
10.29amRussia's Ekaterina Galitskaya ended up third, with Ireland's Derval O'Rourke in fourth. Her time of 12.91 second should be enough to see her through as a fastest loser.
10.27amTurkey's Nevin Yanit wins it in 12.77 seconds, while Harper trailing in second.
10.25amNext up over the hurdles is America's Dawn Harper, who is the defending champion from Beijing.
10.23amSecond place went to Tatyana Dektyareva, while Lucie Skrobakova came third in 13.01 seconds.
10.22amA happy Wells talking to BBC Sport: I'm pleased that I got the first round out of the way successfully. I'm so pleased to be able to represent my country.
10.20amEasy for Wells, who wins in 12.70 seconds. "Nice and comfortable" says Steve Cram in BBC commentary. Sums it up perfectly.
10.18amNow heading back to the track, where America's Kellie Wells is preparing to race. She beat gold medal favourite Pearson recently.
10.16amFrom a British perspective, Morse commits a foul with his first throw. Not the best start.
10.16amA quick discus update. Iran's Ehsan Hadadi is already done after just one throw. He has booked his place in the final with a distance of 65.19m.
10.15amEline Berings finished second, with Ivanique Kemp in third. The highly rated Anastassiya Pilipenko stumbled over a couple of hurdles and could only manage a fifth-place finish.
10.13amAustria's Beate Schrott wins it in a not very fast 13.10 seconds.
10.12amHeat two coming up - the heat Ennis would have been running in.
10.10amHaving advanced through to the semis, Porter spoke to BBC Sport: "I just wanted to come out here, be safe, and qualify. That's what I did. My back is fine."
10.08amAlina Talay finishes first in a time of 12.71 seconds, while Zelinka comes second. Porter's time was 12.79.
10.07amPorter finishes third after a really positive start. She faded towards the end, but did more than enough to qualify for the semi-finals.
10.06amThey're back in the blocks...
10.06amWhat a blatant error from Mali's Rahamatou Drame. She's out!
10.05amFALSE START!
10.05amCanada's Jessica Zelinka, who competed in the heptathlon, also goes in this heat. Just seconds away now.
10.03amSo, we're just a couple of minutes away from the opening heat of the women's 100m hurdles heats. Britain's Porter is up first.
9.56amThree more British athletes will be competing in the qualification rounds of the men's discus during the early part of this session. They are Brett Morse, Abdul Buhari and Lawrence Okoye. Let's hope we can have at least one representative in the final. Ideally all three! We're not greedy!
9.52amA Brit that will be running in the hurdles this morning is Tiffany Porter. The 24-year-old has run 12.65 seconds this season. If she can better that slightly then she could be in with a real chance of claiming a medal.
9.46amIt's a shame that Jessica Ennis decided not to compete in the hurdles. She would have given Pearson a real run for her money. However, she's tired and after her exploits over the weekend you can more than understand that!
9.43amIt would be fair to say that Australia's Sally Pearson is the main draw today. She may not run it this morning, but the Australian has been tipped to break the world record in the women's 100m hurdles over the course of the Games.
9.38amThat is closely followed by the men's 800m, before the women's 1500m wraps things up. Excited? Good!
9.37amThe men's discuss and the women's 100m hurdles kick things off at around 10am. Then, at around 10.45am the women go in the shot put.
9.36amSo, what have we got for you this morning then? Well, as mentioned above the next few hours are all about qualifying. Nevertheless, some of the biggest names in athletics will be competing before 1pm.
9.34amMorning all! What a weekend we had. Can the next few days live up to that? Let's hope so!
