The ATW Twelve Hour Endurance Run delivers the full ATW race-day experience in a fun, accessible, and inclusive format that’s all about endurance, strategy, and determination. Set within a vibrant festival environment at St Neots Regatta Meadow, athletes can take on the challenge solo or as part of a team, working together to complete as many laps as possible within the 12-hour time limit. With the most laps completed earning the title of champions, the event combines competitive spirit with community energy, creating an unforgettable atmosphere on and off the course.
Friday kicks off the weekend with the ultimate pre-race celebration. Athletes, friends, and families can arrive early to enjoy the popular pasta party, perfect for fuelling up ahead of race day. On-site camping allows you to settle in, soak up the pre-race buzz, and enjoy live bands on stage, a kids’ funfair, and a well-stocked bar — creating a lively, relaxed atmosphere for everyone.
Saturday is race day, where runners take on the ultimate endurance challenge: a 12-hour continuous run around a 5.3km looped course. Whether competing solo or as part of a team, athletes will manage pacing, rest, and teamwork to maximise their lap count. The course is smooth, scenic, and spectator-friendly, with excellent organisation, regular support, and constant encouragement from the event village, making it an exciting and rewarding test of endurance from start to finish.
Sunday is all about unwinding. If you’ve stayed on-site, you’re welcome to enjoy a well-earned lie-in at the campsite, reflect on your race, and soak up the relaxed post-event atmosphere before heading home.
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.
