The Tokyo 2020 Olympic 10K Marathon Swim test event will be held in Odaiba Marine Park on August 11th 2019 as part of the READY STEADY TOKYO program.

The objective of the Tokyo 2020 READY STEADY TOKYO test events is be provide its management and operations staff with hands-on experience of running events in order to ensure the smooth operation of the Olympics.

Test events are an important part of the wider operational readiness program for the Games which includes comprehensive training and exercises for Tokyo 2020.

One major issue for the Olympic marathon swimmers and FINA is the water quality.

While the American media raised many questions about the water quality of Copacabana Beach at the 2016 Rio Olympics, open water swimming had greater issues at the 2018 Pan Pacific Championships. These Championship 10 km races were moved from Odaiba Marine Park specifically because water quality was a major issue.

The fundamental problem was urban runoff. The water quality at Odaiba varied significantly depending on whether or not it had rained – which is often the case with urban venues around the world. As a result, the venue was moved from Tokyo Bay to Chiba, a neighboring prefecture.

But the Tokyo 2020 organizers promised – and subsequently claimed – to have solved the water quality of Tokyo Bay, the oft-landfilled coastline of the largest industrialized area in Japan – and one of the most populous metropolitan areas of the world.

The Tokyo officials will use underwater triple-layer screens to improve the water’s quality, allowing the focus to return to the athletes.

The 10 km READY STEADY TOKYO event will put the underwater triple-layer protective screens to test.
