Athletes voiced concerns over water quality and temperature at a marathon swimming test event for Tokyo 2020 Sunday, as officials vowed to monitor the situation closely in the run-up to the games.
“That was the warmest race I’ve ever done,” said three-time Olympic medallist Oussama Mellouli from Tunisia after completing the 5km men’s competition.
“It felt good for the first 2km then I got super overheated,” added the 35-year-old, who won gold in the 10km swim at the London Olympics in 2012.
The event started at 7am with the air temperature already over 30 degrees as the Japanese capital swelters through a deadly heatwave.
“The water temperature was high so I’m a bit concerned about that,” said Yumi Kida from Japan, who said she guzzled iced water before the race in an effort to reduce her body heat.
