ATW Odyssey Triathlon

On Saturday, August 8th, 2026, the Odyssey Triathlon returns as the centerpiece of the inaugural ATW First To Full Triathlon Festival. St Neots will transform into an epicenter for endurance athletes from all walks of life to race, revel in camaraderie, and partake in a day filled with unforgettable moments.
The Odyssey is not merely a triathlon; it's a transformative journey through swim, bike, and run against the backdrop of Cambridgeshire’s picturesque countryside. Athletes can choose between full and half-distance options, each offering an unparalleled challenge and sense of accomplishment.
In the Full Odyssey Triathlon, participants will start with a 3.8km open-water swim in the meandering River Ouse, followed by a grueling yet scenic 180km bike ride through Cambridgeshire’s rolling hills and lush landscapes. The day concludes with a marathon run around historic St Neots, where runners will experience the town's charm and vibrant atmosphere.
For those seeking a more accessible challenge, the Half Odyssey Triathlon offers a reduced distance of 1.9km swim, 90km bike ride, and a half-marathon (21.1km) run, providing all the drama and excitement without the full marathon’s rigors.
The festival also features an Aquabike event for those who want to test their limits in swimming and cycling but prefer not to tackle the running portion of the triathlon. Both full and half-distance options are available here as well.
In 2026, organizers have enhanced the course design with athletes’ needs in mind. The bike route features a checkpoint every 45km back at Race HQ, allowing for quick pit stops and support from cheering crowds. Runners will complete five laps of a scenic 5.3km loop that passes through the heart of St Neots multiple times.
Supporters can cheer on their loved ones throughout various points along both bike routes and run courses, with the “Tent of Enlightenment” serving as an energetic hub offering music, food, drinks, and a festival atmosphere all day long.
Generous time limits are set to ensure every participant has ample opportunity to achieve their goals. Full Odyssey athletes have up to 16 hours (with a 10-hour cut-off for swim and bike stages) while Half Odyssey competitors enjoy a more relaxed 14-hour window.
Away from the race course, families can immerse themselves in live music performances, children’s activities, delicious food stalls, and drinks. The lively town of St Neots is just steps away from Race HQ, making it easy to explore local attractions or simply relax amidst the festivities.
For those looking for a more immersive experience, camping spots are available on-site Friday through Sunday night. This allows participants and spectators alike to fully engage with the event’s spirit well beyond race day itself.
All finishers will receive an exclusive Odyssey medal, commemorative t-shirt, and other goodies as part of their reward package. Completing your Odyssey is more than just crossing a finish line; it's about celebrating personal growth and perseverance in a supportive community setting.
This year, the ATW First To Full Triathlon Festival promises to be not only challenging but also inclusive and inspiring for athletes at every level. Whether you’re seasoned or new to long-distance racing, this event offers an adventure that extends far beyond the triathlon itself. Join us on August 8th for your own unforgettable Odyssey.
