About the Event

Return to a legendary UK triathlon venue at the Wimbleball Triathlon Festival, a premier multi-distance event set for Saturday, August 30, 2026, on the stunning shores of Wimbleball Lake in Exmoor. This bank holiday weekend festival revives the iconic course that hosted Ironman 70.3 for a decade, offering athletes a classic, challenging test with a 1.9km swim in the pristine lake, a demanding and "lumpy" bike leg on quiet country roads, and a scenic but tough run around the water's edge. Choose your challenge: the full 70.3 middle distance, a standard Olympic race, or the ultimate iron-distance event, all featuring secure transition, professional timing, and full camping facilities for a complete weekend experience. Part of a larger sports festival with open water swims and running races, it's the perfect destination for athletes and families alike seeking a vibrant, community-focused competition. Secure your entry for a meticulously organised return to triathlon history, where the legendary Wimbleball challenge meets a fresh, accessible festival spirit.
