The three-time half marathon and two-time cross country World champion Kenya's Geoffrey Kamworor has pulled out of the Tokyo Olympics due to an ankle injury.
Kamworor was a medal contender for Kenya at the Tokyo Olympics. In June he won a very tough Kenyan 10,000m title in high altitude with one of the fastest times in the World this year of 27:01.06.
Just last year Kamworor fractured his tibia after he was hit by a motorcycle while training near his home.
"Whenever Geoffrey had challenges in his career, he always came out stronger. I'm convinced it will be the same this time," Trouw added.
"These are obstacles which can come on your way when you come back from a tough injury earlier on. It's only now extremely bad timing," his manager Valentijn Trouw told the BBC Sports Africa.
