Master the Triple with EtchRock Triathlons
From its 1970s roots, a modest 500m swim, 8km cycle, and 10km run, triathlon has evolved into a global challenge. Today’s triathletes tackle Olympic distances (1.5km swim, 40km cycle, 10km run), grueling Ironman races (3.9km swim, 180km ride, 42.2km run), or shorter sprints (0.8km swim, 24km ride, 5km run). Blending swimming, cycling, and running, it’s a dynamic way to stay active and keep training fresh. EtchRock brings you the UK’s best triathlon events for 2025 2026, from mini-triathlons to Ironman epics, with detailed listings and real-time updates. Ready to test your limits? Find your race and conquer the three today!
