The elite Mixed Relay format, also known as 4 x Mixed Relay, consists of teams of four, comprised of two men and two women. Races last between an hour and ninety minutes depending on the course layout and are very explosive and exciting to watch.
Each athlete completes a mini triathlon before tagging their team mate. The mini triathlon format can vary but is normally set at course distance of around 300m swim, 7.5km bike, 1.5km run.
The Mixed Relay format was introduced by the ITU in 2009 after merging the previously individual men's and women's mixed relay titles. The event was initiated with the aim of increasing the profile of the sport to get more triathletes, as well as introducing the team discipline to the Olympic Programme.
The Glasgow Commonwealth Games in 2014 was the first time the event featured as a major multi-sport games, where English quartet Vicky Holland, Jonathan Brownlee, Jodie Stimpson and Alistair Brownlee taking the gold medal.
Triathlon Mixed Relay will make its Olympic debut at the Tokyo 2020 Games, making the event in Nottingham a top priority for teams looking to secure the first points on offer to qualify their spots on the start line. The Accenture World Triathlon Mixed Relay Nottingham was named by the ITU as the first of two qualification events taking place in 2018, in addition to the Mixed Relay World Championships and the Continental Championships.
