Relay triathlons in the UK

Relay triathlons are a great way to experience the atmosphere of a triathlon without taking on all three legs of the standard event and without the hassle of the transitions. Each team member takes on one of the three legs - the swim, the bike or the run - and leaves the other legs to their team members. Put together your dream team and have a go!
