ATW Oundle Triathlon Sprint distance will host the 2026 East Region Adult Race Series.

ATW is the largest triathlon organiser in the UK and we are bringing you the Oundle Triathlon!

It doesn’t matter if you are an experienced triathlete, or this is your very first attempt at swim-bike-run… this is an ideal event for you!

This is an opportunity to race in one of only a handful of indoor 50m pools in the country before completing the bike on the beautifully rolling country roads to the North of Oundle and finishing with a run round the grounds of the exclusive Oundle School.

Every participant will be individually chip-timed whilst tackling their choice of the following distances :

Supersprint: 400m swim – 13km bike – 2.6km run

Sprint: 600m swim – 25km bike – 5.3km run

The transition is on a grass playing field, the draft-illegal bike will be on the open roads and the run will be around the beautiful playing fields.
