ATW Stewartby Lake Triathlon & Aquabike

About this event

Stewartby Lake hosts a well-organized triathlon and aquabike event that's earned a reputation for its impressively fast, flat course. The day starts with a swim in calm, clear lake waters, followed by a lapped road bike segment that riders consistently praise for its speed-friendly profile. Aquabike participants finish after the bike leg, while triathletes continue with a traffic-free run through Marston Vale Country Park. The venue offers a proper mix of challenge and accessibility — the standard distance suits experienced multisport athletes, while the sprint option welcomes those newer to racing. With its smooth logistics and supportive atmosphere, it's the kind of event that keeps people coming back year after year.
