The Frenchman surrendered after an hour and twenty minutes of racing.

Defending Frenchman Yohann Diniz left Saturday in Doha for the 50-kilometer march of the World Athletics Championships, exhausted by conditions (about 31 degrees and 75% humidity).

Diniz (41) has surrendered after an hour and twenty minutes of racing, having traveled fifteen kilometers in the sweltering heat of Doha, although the event began at 23:30 local.

He had criticized the conditions of the event

In the week, the French had criticized the conditions of the test in the "furnace" of Doha. The world record holder of the distance since 2014 (3:32:33) was still the favorite of the Worlds as the best performer of the season.

Diniz had already dropped out at the 2008 Olympics in Beijing and had made a spectacular save at the Rio Games in 2016, a race he had finished in 8th place.
