ATW Stewartby Lake Triathlon & Aquabike

ATW Stewartby Lake Triathlon & Aquabike takes place at the Stewartby Sailing Club in Bedford, offering a superb venue for multisport racing with calm open-water swimming and fast, flat bike routes. Celebrated for hosting a sold-out GB team qualifier in 2023, the event is designed to be both PB-friendly and welcoming for first-timers. Participants can expect professional event commentary, clearly marked courses and supportive, experienced marshals guiding the way. Parking is available opposite the venue for a small charge, helping to keep logistics simple on race day.

The triathlon features a scenic, traffic-free run along the lakeside paths of Marston Vale Country Park, while aquabike competitors complete their race at the entrance to transition before heading to the finish arch. Finishers are rewarded with a custom-designed, unique medal, alongside free event photos and post-race snacks and goodies. The course’s flat profile and lapped bike section make for rapid racing, ideal for those chasing times as well as those seeking an enjoyable and well-supported experience. With friendly organisation and a focus on athlete experience, this event blends speed, scenery and smooth operations.
