ATW Grafman Middle Distance Triathlon

Join us at the beautiful and iconic Grafham Water for one of the UK’s most popular middle-distance swim-bike-run events, proudly delivered by triathletes for triathletes. The ATW Grafman Triathlon has a prestigious history, having been voted National Event of the Year in 2014, and hosting the Triathlon England Middle Distance Championships in 2015 and 2023, as well as the British Championships in 2016. Open to athletes of all abilities, this draft-illegal race challenges participants with a 1.9K swim featuring an ‘Aussie style’ mid-swim exit, a 90K bike ride through quiet country lanes, and a scenic 21K run with stunning views of Valve Tower. For those preferring to skip the run, the Aquabike option offers a swim-bike race finishing back at transition. The event includes well-marked courses, water and nutrition stations, and a custom-designed medal for finishers.
