Welcome to the ATW St Neots Triathlon. Make 2027 your year and take on the Super Sprint, Sprint or Standard distance at this beautiful venue.

Whether you are an experienced athlete looking for a very fast time, or you are a novice competitor looking for a safe and friendly venue for your first open water triathlon, then the ATW St Neots’ triathlons are ideal.

The swim takes place in the beautiful River Ouse, followed by a bike course that takes you through some of the most scenic villages in the area finishing with a run around the Riverside Park. The venue has very easy access to the local town that is a two minute walk away.

This is a draft illegal (non-drafting) race with an option of a Super Sprint (400m swim, 8km bike, 2.5km run), Sprint (750m swim, 24km bike, 5km run), Standard distance (1500m swim, 45km bike, 10km run) and Standard distance Aquabike. There is also the chance to team up with friends for a standard distance relay, with one person completing each discipline.

The triathlons will begin from 9:15AM
