Triathlon

A triathlon is a multi-sport endurance event consisting of swimming, cycling, and running in immediate succession over various distances. Triathletes compete for fastest overall course completion time, including timed "transitions" between the individual swim, bike, and run components.

Triathlon races vary in distance. The medium in difficulty is called "Olympic distance" (1.5 km swim, 40 km ride, 10 km run,) but the Ultra Distance (3.8 km swim, 180 km ride, and a marathon: 42.2 km run) is a killer. They don't call that Ironman triathlon for nothing.
