Take on a classic British multisport festival at the ATW Big East & Maldon Triathlon, the largest event of its kind in the UK, on Saturday, May 16, 2026. Set in the historic and scenic Essex coastal town of Maldon, this comprehensive event offers a challenge for every athlete, from the epic Middle Distance (Half-Ironman) triathlon to Standard, Sprint, Aquabike, and relay options. The day begins with a unique and challenging 1.5km swim in the tidal River Blackwater, timed to start with the high tide for the best possible conditions, offering a truly distinctive open-water experience. Cyclists are then rewarded with a fast, non-draft legal bike course through the quiet, flat lanes of the beautiful Dengie Peninsula, while the flat, multi-lap run along the Maldon Promenade provides fantastic spectator support and sea views. Known for its superb organization by the UK's largest triathlon organiser and its welcoming, community-focused atmosphere, it's the perfect goal for first-timers and seasoned competitors alike. With a late-morning start encouraging a social post-race atmosphere and a flexible transfer policy that puts athletes first, it's an event designed by triathletes for triathletes. Whether you're chasing a personal best over the middle distance or tackling your first sprint, this event delivers a memorable and well-supported race day in a truly special setting.
