I don’t know if his comments have been reported here but here it is.
Renato Canova, the veteran Italian athletics coach, said he expected Chepng’etich to slap a new world record in Chicago.
“I expected a clear attack on the world record. I expected something slightly better than Ethiopia’s Tigst Assefa’s world record, just around 2:11:30. At the end, the performance was a surprise looking at the entity of the improvement. Without any doubt, the new shoe technology can give a good advantage (more for women than for men) in racing.
