The event that combines swimming, cycling, and running in one competition is known as a triathlon. Participants compete in three continuous segments: they begin with the swim, followed by cycling, and finisher with a run. Triathlons vary in distance but commonly feature a standard Olympic distance of 1.5 km swimming, 40 km cycling, and 10 km running. This sport tests not only endurance and speed but also transitions between activities, making it unique and challenging.
