【Tokyo Olympics, Coverage from Hokkaido Venue (8)】 Women’s Marathon: 15 Athletes withdraw in extreme heat despite earlier start


The Women’s Marathon was held on August 7, the third day of the Tokyo Olympic Games athletics Marathon and Race Walk events being held in Sapporo. Temperatures in Sapporo were extremely hot, with a maximum of 31.9 degrees recorded just before noon. This was the 18th consecutive day on which temperatures of at least 30 degrees were recorded. Despite the games’ Organising Committee hastily changing the start time to one hour earlier at 6 a.m., the race proved tough, with 15 of the 88 starters withdrawing before the end of the race.
Between the night of August 6th and the early hours of the 7th, a ‘tropical night’ – when the lowest temperature is at least 25 degrees – was recorded in Sapporo. At 6 a.m. when the race started, the temperature was 25.9 degrees, and a humid 79%. The Marathon and Race Walk events were moved to Sapporo to avoid the heat of Tokyo but, on this day, temperatures from the middle of the race onwards were almost identical to those in Tokyo. Humidity was lower than that of Tokyo but continued at around 70%.
As the top runner finished at around 8:30 a.m., the temperature was 29.1 degrees, with 68% humidity. Japanese competitor Honami Maeda (25, Tenmaya team), who has experience of running the summer Hokkaido Marathon, finished 33rd. “It was hotter than I expected,” she recalls.
Meanwhile, the temperature at 9:10 a.m. – when the last competitor to complete the race in 73rd place crossed the line – was over 30 degrees, and the effects of moving the race one hour ahead of schedule could be seen to some extent. Bronze medalist Molly Seidel (27) from USA appraised the decision, saying “It was hot and humid so it was the right decision to move the start forward one hour.”
