Great Britain's Charlie Grice has admitted that he was delighted to have reached the men's 1500m final after only progressing through to the semi-finals in fortunate circumstances.
Grice was hampered during his heat and an official ruled that it had denied him the chance of qualification but on Thursday night, Grice ran a superb race to finish in fifth spot to gain an automatic place in Saturday's final.
The 22-year-old told BBC Sport: "I am so happy to get through. When the pace was slow I was quite nervous but I knew my 800m speed was good. I told myself to stay patient and I am glad I redeemed myself because Tuesday was not me.
"A few times people were cutting in, so I am just glad I stayed on my feet. I wanted to make sure I proved myself today. It was close but I am thrilled. Two days to rest up and the final will be a cracker."
Last year, Grice finished in ninth place in the World Championships final.
