Triathlon at the 2020 Summer Olympics – Mixed relay

The Mixed relay triathlon at the 2020 Summer Olympics took place at the Odaiba Marine Park in Tokyo on 31 July 2021.

The mixed team event featured teams of four (two men and two women). Each athlete performed a triathlon of 300 m swim, 6.8 km cycle, and a 2 km run in a relay format.

Kristian Blummenfelt and Flora Duffy, gold medallists in men's and women's individual events, were unable to participate since Norway and Bermuda failed to qualify four athletes, while Austria and South Africa were forced to scratch as they were unable to field a team due to athletes being injured during individual events.

Alex Yee, silver medallist of the men's individual event, brought Great Britain home for the gold. Morgan Pearson and Vincent Luis anchored the silver and bronze for the United States and France. Mexico's Irving Pérez finishes the race as the last athlete while Russia's Igor Polyanski tests positive for doping and receives 3-year suspension in October 2021, jeopardizing the country's rank in the event.
