Olympics: Tokyo 2020 marathons to start one hour earlier owing to heat fears

TOKYO (REUTERS) – Next year’s men’s and women’s Olympic marathons will start at 6am local time (5am in Singapore) to try to avoid the worst of Tokyo’s blazing summer heat, organisers said on Tuesday (April 16).

The marathons had been scheduled to begin at 7am but with temperatures reaching over 40 deg C last year, organisers were under pressure to make changes to ensure the safety of athletes and supporters.

The 50km race walk final has also been moved to 5.30am local time to avoid the midday sun.

A record heatwave last year killed over a dozen people in Tokyo with July average temperatures reaching more than 30 deg for the first time since 1998, according to the Japanese Meteorological Agency.

Athletes focus on developing a strong circadian rhythm to perform at their best during competition and will have to amend their schedules for this ultra-early start time.

Tokyo 2020 organisers said the changes had been ratified by the International Association of Athletics Federations (IAAF).

“We have an approval from the IAAF athletes commission, (so) it is understood we have approval from athletes,” said 2004 Olympic hammer throw gold medallist Koji Murofushi, who is sports director at Tokyo 2020.

The schedule was also noticeable for the number of finals taking place in the morning, partly due to the heat as well as considerations for US broadcasters wanting showpiece events in prime time.

Nine athletics finals will be held in the morning, while basketball and swimming will also feature medal events in the morning.

“By looking at the Olympic schedule as a whole it should be observed that one gave consideration to local, Japanese, as well as global audiences,” Murofushi said.

“Also, I hear that athletes are saying it is possible to condition if they know the schedule in advance, so I think that they should condition themselves to do their best at Games time.”

Women’s softball will be the first event of the Olympics, in Fukushima on July 22, two days before the Opening Ceremony that will start at 8pm on a Friday night.

The women’s 10m air rifle is the first medal event of the Games, starting at 8.30am on July 25.
