Doctors issue heat warning for Olympics

A group of Japanese doctors yesterday urged Olympic organisers to start the Tokyo 2020 marathon as early as 5.30am, saying failure to do so could “lead to deaths” from heatstroke.

The warning is the latest in a chorus of concern about how extreme heat could affect several sporting events at the Olympic Games, particularly after Tokyo sweltered through a record heatwave this year. Organisers have acknowledged the concerns and already moved the marathon start time to 7am. (AFP)
