Mixed Relay is set to feature for the first time at the Tokyo 2020 Olympic Games, and five Olympians were part of the action in Nottingham. An initial 300m swim in the River Trent was followed by a 7.5km bike ride and 1.5km run before athletes handed over to their next team mate to do the same again. In total, seventeen teams of four athletes took part, including international teams from Japan, Germany, Australia and Canada.
