As the Official Mixed Relay Partner, Accenture supports British Triathlon’s Mixed Relay elite events across the UK. The Mixed Relay format is racing at its most thrilling. It’s energetic, exciting, uncompromising and action-packed. The innovative format also known as 4XMixed Relay, comprises two men and two women. Each athlete completes a ‘super-sprint’ triathlon of swimming, biking and running, before tagging their next team mate in a relay race. It’s non-stop action from the very beginning, and the pace is relentless. It is survival of the fastest. The format will be included as an Olympic event for the first time in the Tokyo 2020 Olympic Games.

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 format has been quickly adopted globally, and was placed on the programme of the 2010 Singapore Youth Olympic Games, with great success. The International Triathlon Union is passionate about having Triathlon Mixed Relay added to the Olympic programme, as the format appeals tremendously to youth. With numerous lead changes, lots of unpredictable drama and the display of team pride, the discipline develops the sport among new generations and new audiences. Additionally, the mixed relay format promotes gender equality in sport, showcasing that men and women can practice the sport together on the same field of play.

Each athlete completes a super sprint triathlon before tagging their team mate. The sprint triathlon format can vary but is normally set at course distance of around 300m swim, 7.5km bike, 1.5km run. Races last between an hour and ninety minutes depending on the course layout and are very explosive and exciting to watch.
