The Olympic marathon swimming, also known as open water swimming, will be in the second half of the Games, which runs from 24 July – 9 August 2020.

The women’s 10km race will take place on the 5 August, before the men’s 10km race the following day.

Odaiba Marine Park offers visitors a rich harmony of natural greenery, the ocean and stunning views of Tokyo’s futuristic cityscape including the nearby Rainbow Bridge. The venue will also host the Olympic triathlon events, as well as the para-triathlon at the Paralympic Games.

Open water swimming is the most recent aquatic sport to be included in the Olympic schedule. The sport was introduced at the 2008 Olympics in Beijing, with Team GB landing silver (Keri-anne Payne) and bronze (Cassandra Patten) in the women’s event.

While Britain’s swimmers have failed to medal since the inaugural staging of the event, Jack Burnell was harshly penalised at the last Olympics in Rio when interference from another swimmer cost him a shot at gold.
