What is Triathlon?
A triathlon is a multi-sport event involving the completion of three continuous and sequential endurance events. Triathlon involves swimming, cycling, and running in immediate succession over various distances. Triathletes compete for fastest overall course completion time.
Triathlon races vary in distance. The main race distances are Sprint distance (750 m swim, 20 km bike, 5 km run), Olympic distance (1.5 km swim, 40 km ride, 10 km run), the Half Ironman (1.9 km swim, 90 km ride, 21.1 km run), and the Ironman (3.8 km swim, 180 km ride, and a marathon 42.2 km run).
Transition areas are positioned both between the swim and bike segments (T1), and between the bike and run segments (T2) and are where the switches from swimming to cycling and cycling to running occur. These areas are used to store bicycles and any other accessories needed for preparing for the next stage of the race. The time spent in T1 and T2 is included in the overall time of the race.
