The intrigue in men’s events at the world championships is focused on the track, where Usain Bolt and Mo Farah say farewells and Wayde van Niekerk eyes a sprint double.
The 10-day meet begins Friday and runs through Aug. 13 at London’s Olympic Stadium.
Bolt plans to retire after worlds, where he will race the 100m on Friday and Saturday and the 4x100m the following Saturday. The 30-year-old has slowed every year since his 2009 world records, but his competition may be at its weakest ever this year.
Plus, Bolt has narrowed his focus.
