He won his heat in 9.74 seconds with a 1.7 m/s tailwind, which falls inside of the guidelines set by the IAAF, Track & Field’s international governing body.
“I was nervous in Osaka because I did not compete much this season (before the champs). I forgot how I should have run in the last 40m of a race.
“I will not say today was a revenge after Osaka. There the expectations were too high. I thought too much about the World record, but I have have done a lot of work in the last two weeks. I learnt again to run from the start and to be more relaxed.”
I am happy to see that my prediction on May 30th this year came true and that he did set a new record this season.
