Triathlon is a demanding and complete sport that combines swimming, cycling and running in a continuous sequence. Born in the 1970s in California as an alternative to track training, this sport quickly became globally popular, with its inclusion in the Olympic Games in 2000. Triathlon tests not only physical endurance, but also mental strength and the triathlete's ability to adapt. It is practiced in varied environments, from the sea to lakes for swimming, from roads to countryside for cycling and running. Triathlon formats vary considerably, offering challenges for all levels. The XS (Supersprint) format is ideal for beginners, with short distances (400m swim, 10km bike, 2.5km run). The S (Sprint) format is the most popular among amateurs (750m swim, 20km bike, 5km run). The M (Olympic) format is the one used at the Olympic Games, with distances of 1.5km swim, 40km bike and 10km run. For more experienced athletes, the L, XL, Half Ironman (also known as 70.3) and Ironman (also known as XXL) formats represent the pinnacle of endurance. The 70.3 combines 1.9km swim, 90km bike and 21.1km run (a half marathon), while the Ironman is famous for its extreme distances: 3.8km swim, 180km bike and 42.195km run (a full marathon). Transitions between disciplines are called T1 (swim-to-bike) and T2 (bike-to-run) and are key moments in the race where athletes must be quick and efficient. To prepare for a triathlon, rigorous planning is necessary, incorporating specific sessions for each discipline as well as brick sessions to get the body used to switching from one sport to another. Equipment is also crucial: a wetsuit, a suitable bike, running shoes and a helmet are essentials for successful participation. The atmosphere of a triathlon is unique, blending competitive spirit and friendliness. Whether you are a seasoned athlete or a beginner looking for a challenge, our triathlon calendar will help you find the perfect event.
