A triathlon is a type of sport that combines three activities - swimming, cycling, and running. People who participate in triathlons typically swim a certain distance, then ride a bike for a certain distance, and finally run a certain distance, all one after the other without stopping. Triathlons can take place in a variety of settings, such as in a pool, in open water like a lake or ocean, and on roads or off-road trails. It is a popular sport that requires endurance, strength, and mental toughness.
