The mixed team event featured teams of four (two men and two women). Each athlete performed a triathlon of 300 m (330 yd) swim, 6.8 km (4.2 mi) cycle, and a 2 km (1.2 mi) run in a relay format.[3]
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.
