Olympic heptathlon champion Jessica Ennis-Hill has admitted that she is looking forward to the "test" of the upcoming Anniversary Games.
Ennis-Hill, who will be competing in the long jump and 100m hurdles on Saturday, said that the event will go a long way to see whether she is fit for the world championships in August.
"I think it's going to be a big test to firstly do the hurdles and then go to the long jump afterwards. That will simulate what I will have to do in Moscow," Sky Sports News quotes her as saying.
"Tuesday was the first test, but I had a good response. This is the next big test with the hurdles. It is explosive and I come down with my lead leg on the damaged Achilles. It will be good to see how it goes and how it responds the day after.
"I definitely feel in a better position than I did last week and the week before, but I have just started doing my explosive work this week. This week I have done two hurdles sessions and I hadn't hurdled for five or six weeks and I haven't been able to sprint."
The Anniversary Games are the first event at the Olympic Stadium since the London Games.
