Putting it simply, it’s an event consisting of three parts: swim, bike, run. It’s almost always in this order and it always has these three parts. The biggest differences in the triathlons are the distances of the races. Here are some general standard race lengths:
Sprint: 750m swim, 20km bike, 5km run
Olympic: 1500m swim, 40km bike, 10km run
Half Ironman: 2km swim, 90km bike, 21.1km run
Ironman: 3.8km swim, 180km bike, 42.2km run (ie. a full marathon)
Ultraman: a three-day event that totals: 10km swim, 420.2km bike, and 84.3km run
Most races consist of an open-water swim, but some sprints are in a pool depending on the time of year.
