A triathlon is a multi-sport race that combines three different activities: swimming, cycling, and running. Participants compete in this challenging event by completing each segment one after the other, testing their endurance and versatility. The race usually starts with a swim, followed by a bike ride, and finishes with a run, making it a true test of physical fitness. Triathlons come in various distances, catering to different skill levels. The most common formats include the Sprint, Olympic, Half Ironman, and Ironman distances. Athletes often train for months to prepare, focusing on improving their performance in each discipline to achieve their best overall time.
