What is a Triathlon?

A triathlon is a multi-sport event involving the completion of three continous sporting disciplines. The most popular version of a triathlon is the swim, bike and run format. Triathletes compete for the fastest overall completion time including 'transitions' between the swim, cycle and run components.
