About the Event

Conquer a classic British middle-distance triathlon at the iconic ATW Grafman on Sunday, June 7, 2026. Held at the beautiful Grafham Water, this event has earned its stellar reputation, having hosted national and British championships, and delivers a true "by triathletes, for triathletes" experience. You'll take on a 1900m open-water swim with a unique 'Aussie style' exit, followed by a 90km bike leg on quiet country lanes and a scenic 21km run with stunning views of the reservoir's valve tower. The event is designed for everyone, offering a draft-illegal individual race, a relay option, and an Aquabike challenge for those who want to skip the run. Enjoy the full weekend experience with on-site camping and accommodation, perfect for bringing your family along to cheer you on. From supportive marshals and well-stocked aid stations to a custom finisher's medal and finish-line goodies, every detail is crafted to help you achieve your goal. Organised by Active Training World, this community-focused event offers a hassle-free transfer policy and supports Alzheimer's Research UK. Whether you're a first-timer or a seasoned competitor aiming for the 9.5-hour cutoff, the Grafman provides the perfect stage to test your limits at one of the UK's most popular middle-distance triathlons.
