Join us at the beautiful and iconic Grafham Water to experience one of the country’s most popular middle distance swim-bike-run events, delivered by triathletes for triathletes.
ATW Grafman was voted National Event of The year 2014, hosted the Triathlon England Middle Distance Championships in 2015 and 2023 and the British Championships in 2016.
This event is open to everyone, regardless of ability and there are plenty of activities at the venue to keep the whole family entertained while you race. There is an overall cut off time for the event of 9 hrs 30 mins.
This race has a draft illegal bike leg.
For those wanting the challenge of the Swim-Bike, but without the run, take on the Grafman Aquabike, with your race finishing at the entrance back in to transition after the bike leg.
