Triathlons

Triathlons combine swimming, cycling and running into one of the most popular all-round physical challenges. There are a huge variety of types of triathlons to choose from in terms of distances, cycle and run terrain options, and whether the swim is in a pool, in open water (eg lake) or even the sea.

Triathlon distances:
Super Sprint Triathlons: 400m swim; 10km bike; 2.5km run.
Sprint Triathlons: 750m swim; 20km bike; 5km run.
Olympic Triathlons (aka Standard Triathlons): 1500m swim; 40km bike; 10km run.
Half Ironman Triathlons: 1.9km swim; 90km bike; 21.1km run. (This distance is also known as a “70.3” which refers to the total race distance in miles.)
Ironman™ Triathlons: 3.86km (2.4 mile) swim; 180.25km (112 mile) bike; 42.2km (26.2 mile) run. As Ironman™ is a trademark, these are also known as ‘Iron distance’ events.
