Triathlon et Duathlon du Colosse is a multisport race series in Saint-André, on Réunion’s east coast, based at Parc du Colosse. The program offers triathlon and duathlon options, allowing athletes to choose between swim-bike-run or run-bike-run formats. The Triathlon Club de Saint-André organizes the event for both regular triathletes and those seeking a shorter local challenge.
The course utilizes the park and extends toward Ravine Creuse, providing a compact Saint-André setting instead of a point-to-point feel. Formats include youth races, XS triathlon, M triathlon, and M duathlon, with results and course details maintained across editions. This structure creates a club-run race day with multiple starts rather than a single mass event.
