Join us on Sunday September 12th 2027 for the Reading Triathlon, Aquathlon and Aquabike. The Reading Triathlon was the birthplace of triathlon in the UK, with the first official British Triathlon National Championships held at the Kirtons Farm Water Sports Centre in 1983. Tri2O Triathlon Club proudly hosts the Reading Triathlon, a race organised by triathletes with the best race experience in mind – still at the original venue!

This year, we’re returning with seven fantastic race options: the old favourites Sprint, Standard, Sprint Relay, Aquathlon and Aquabike. And we have added two new exciting options; Super Sprint and Sprint Aquabike

Super Sprint400 m swim, 12 km cycle, 1.8 km run
Sprint 750 m swim, 22 km cycle, 5.4 km run
Standard1500 m swim, 40 km cycle, 10.8 km run
Sprint Relay As Sprint, but with 2-3 participants in a team
Aquathlon750 m swim, 5.4 km run
Standard Aquabike1500 m swim, 40 km cycle
Sprint Aquabike750 m swim, 22 km cycle

Experience the exhilaration of an open water swim in the beautiful H2O Swim Centre lake, followed by a picturesque cycle course through the quiet local lanes of Burghfield, Mortimer, Silchester, Bramley, Stratfield Saye and Grazeley (both Sprint and Standard are single loop), before finishing with an off-road run around the lakeside track.

The Reading Triathlon is conveniently located just off the M4 with ample parking and proximity to Reading Green Park Station. The triathlete-led event team prides itself on its friendly and welcoming atmosphere and this well-organised event suits beginners and experienced triathletes alike.

As a club-run event, our primary focus is the athlete experience; all proceeds from the event are shared between reinvestment in the club to support activities for members, significant donations to charity, and where possible a small contribution to volunteers to say thank you for their efforts. We are supporting local charity “Sport in Mind”, whose mission is to transform the lives and mental health of children and adults through sport and physical activity. For more information please visit their website.

We are also supporting the charity Women in Tri UK, whose aim is to help more women get into triathlon by removing barriers, offering support, and empowering first-timers and beginners to take the plunge. We are delighted to be working with this fantastic volunteer-led charity as Silver Event Partners!
