Olympic marathons set to move out of Tokyo to cooler north

Amid concern about the expected searing heat in Tokyo, the IOC wants to move the 2020 Olympic marathons 800 kilometers (500 miles) north to find cooler and safer race conditions.

The International Olympic Committee detailed a new plan Wednesday to stage the marathons and race walking events in Sapporo, the host city of the 1972 Winter Olympics, which "will mean significantly lower temperatures for the athletes."

The proposal comes weeks after marathons were run around midnight in 38 degrees C (100 degrees F) at the track and field world championships in Doha, Qatar.

Forecast temperatures in Sapporo are "five to six degrees centigrade cooler during the day than in Tokyo," the Olympic body said.

Still, one Olympic medal contender affected by the plan questioned if athletes were consulted.

An Olympic panel has been consulting with sports governing bodies while assessing heat and weather issues for the July 24Aug. 9 Tokyo Games.

The marathons were already due to start at 6 a.m. in Tokyo to ease the heat effect on runners. The men's 50-kilometer race walk final was slated for a 5:30 a.m. start.

The IOC said it informed the governing body of track will also consult Olympic teams and broadcasters.

In Doha, 28 of 68 starters failed to finish the women's marathon and 18 of 73 men failed to complete the course.

Ethiopian distance-running great Haile Gebrselassie said athletes "could have died" in the women's race.

An Olympic panel overseeing preparations will discuss heat measures at its Oct. 30-Nov. 1 meeting in Tokyo.

The plan driven by increasing summer heat cuts into a key promise of Tokyo's bidding, first for the 2016 Olympics won by Rio de Janeiro and then its successful 2020 campaign, to deliver a "compact games" with 85% of venues in an 8-kilometer (5-mile) city center cluster.
