Croydon Harrier James Dasaolu is aiming to post a season's best at Hanžekovic Memorial IAAF World Challenge in Croatia tomorrow (Tuesday).

In his first outing since the Rio Olympics, the 29-year-old clocked 10.21 seconds for a fourth place finish in men's 100m at ISTAF IAAF World Challenge last Saturday in Berlin, Germany.

Kim Collins, the evergreen 40-year-old former world champion from St Kitts & Nevis, won in 10.07secs, while current British number one Joel Fearon followed in 10.16secs - well below his best of 9.96secs - and France's Rio Olympic bronze medalist Christopher Lemaitre was third with 10.19secs.

"I got a sluggish start, but I was really happy with the second part of my race," said Dasaolu.

"So if l could get a good start and put a second part of the race together hopefully that will lead to a season's best in my next race."
