Triathlon Mixed Relay consists of teams of four athletes: two men and two women, who will compete in the order of woman, man, woman, man. Each athlete completes a super-sprint triathlon of swimming, biking and running, in Stockholm a 300m swim, 6km bike and 2km run, before handing over to their next team mate. The first team across the finish line is the winner.
There have been four editions of the ITU Mixed Relay World Championships. Switzerland won the first two titles, in 2009 and 2010, before Great Britain's dream team won it in 2011.
The Mixed Relay is a stadium event focused around the transition zone, with the athletes retuning on average every five to eight minutes creating a special atmosphere and memorable moments for committed fans and television viewers alike. The short distances, and numerous transitions results in non-stop action from start to finish, with the possibility of upsets at any stage. The relay format made its major games debut at the inaugural Singapore 2010 Youth Olympic Games, and has been included on the programme for the 2014 Glasgow Commonwealth Games and the 2014 Incheon Asian Games.
