About Triathlon

Triathlon is a multi-sport event in which participants complete a continuous swim, cycle and run, with transitions in between to change kit.

There are various distances, such as sprint, middle and long. Disability triathletes compete in paratriathlon and there are also duathlons and aquathlons.

Triathlon = Swim + Bike + Run

Duathlon = Run + Bike + Run

Aquathlon = Swim + Run

Swimming can be pool-based or in open water such as the sea, lochs or reservoirs. Cycling is mainly non-drafting but some events allow drafting – a technique to reduce wind resistance where you ride in a pack.  Runs can be on tarmac or country terrain.

Triathlon events are often split into elite races and age group races for keen amateurs. Due to the variety of distances and formats, triathlon attracts people of all ages and abilities to take part.

  • You will need some kit: swimming goggles, a wetsuit (for open water events), a bike and a pair of trainers.
