The Olympic distances for individual races are:
- Swim: 1500m (open water)
- Bike: 40km
- Run: 10km
In the mixed relay, teams comprise two men and two women, each of whom completes a short-course (super-sprint) triathlon one at a time, always in the order of female-male-female-male. The winner is the team whose fourth competitor crosses the finish line first. Distances for this event are:
- Swim: 300m (open water)
- Bike: 8km

Since debuting at the 2000 Sydney Games, triathlon has produced medalists from a variety of nations. Great Britain, Switzerland and Australia lead the overall standings with five. Gwen Jorgensen won the women’s event at the 2016 Rio Games to give Team USA its first Olympic gold in the sport.
