Lord Coe was a two-time Olympic gold medallist but never competed in a World Championships
World Athletics president Lord Coe says the location of warm-up facilities at the World Championships in Tokyo is "not perfect", following complaints from athletes including Great Britain's Keely Hodgkinson.
Yoyogi Park, where the main warm-up facility is located, is a two and a half kilometre drive from Japan National Stadium, a bus journey which takes about 15 minutes.
It means athletes are catching a bus around an hour before they compete, with Olympic 800m champion Hodgkinson describing the situation as "draining".
Coe says transport and logistics have been a challenge but the organisers have done their best.
