Reading Triathlon, Aquathlon & Aquabike
Race at the home of Triathlon in the UK
Entries now open for this year’s Reading Triathlon, Aquathlon and Aquabike! Enter here.
Join us on Sunday September 14th 2025 for the Reading Triathlon, Aquathlon and Aquabike. The Reading Triathlon was the birthplace of triathlon in the UK, held at the Kirtons Farm Water Sports Centre in 1983. Tri2O Triathlon Club proudly presents the Reading Triathlon, a race organised by triathletes for triathletes – still at the original venue!
This year, we’re excited to offer five fantastic race options, including Sprint, Standard, Sprint Relay, Aquathlon and Aquabike.
| Sprint | 750 m swim, 22 km cycle, 5 km run |
| Standard | 1500 m swim, 40 km cycle, 10 km run |
| Sprint Relay | As Sprint, but with 2-3 participants in a team |
| Aquathlon | 750 m swim, 5.4 km run |
| Aquabike | 1500 m swim, 40 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 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. The triathlete-led event team prides itself on its friendly 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 have decided to support a local sport-focussed charity “Sport in Mind” this year, whose mission is to transform the lives and mental health of children and adults through sport and physical activity.
