Grafham Water Visitor Center, Huntingdon

The Odyssey at Grafman Triathlon will once again deliver the full ATW experience, an unforgettable middle-distance challenge approved and regulated by British Triathlon. Now part of the Odyssey Triathlon Series from 2026, this event promises an electric atmosphere, a welcoming event village by the water, and a weekend built around the spirit of adventure, camaraderie, and endurance.

Saturday offers athletes the opportunity to visit the event village, pick up their race pack, and get ready for the weekend. It’s a relaxed chance to speak with the ATW team, ask any last-minute questions, and enjoy the pre-event atmosphere before Sunday’s race.

Sunday morning athletes will tackle the 1900m swim, 90km bike, and 21km run to complete the Grafman Middle Distance Relay. The course features rolling terrain and mixed surfaces, ideal for those seeking a rewarding and memorable race experience.

We’re always on the lookout for amazing people to join our ATW Volunteer Team the heartbeat of every event and the ones who make the magic happen. Our volunteers bring the energy, encouragement, and smiles that make race day so special for every athlete. Whether you’re handing out medals, helping at registration, or cheering from the feed stations, you’ll be part of a supportive crew that makes a real difference. Volunteering is a fun, rewarding way to experience the event up close, meet new people, and be part of the ATW family.
