Competitors race against the clock which starts as they begin the swim and stops as they cross the finish line after the run. Race distances vary depending on age and preference. Maximum distances are set for children but adults can choose to race over a number of distances.
The kit you need for swimming, swimsuit and goggles. For riding, any bike in good working order and cycle helmet. For running, trainers, t-shirt/vest and shorts.
Triathlon is a great way to get active and, by taking on the three elements of swimming, cycling and running you can keep it fun and varied too.
