Event overview
Whether your child is a budding Alex Yee or Georgia Taylor-Brown, or trying triathlon for the first time, this is the perfect event for them.
Competitors will swim in one of the UK’s few indoor 50m pools before taking on the bike and run in the beautiful grounds of Oundle School. The 50m ‘snake swim’ sees the fastest athletes start first, with individual timing beginning as they enter the water. Accurate predicted swim times ensure smooth seeding and a fair race.
Transitions take place on grass, followed by bike laps of the playing fields — 2km loops for most categories and an 800m cut-off for TriStart — before a run on 600m tarmac laps around the tennis courts. The event finishes on the playing fields, where every finisher receives a medal, water and goodies.

Overview
The Oundle Children’s Triathlon takes place within the secure, scenic grounds of Oundle School, providing a safe and exciting environment for young athletes. The event begins with a ‘snake swim’ in a 50m indoor pool, where swimmers start in order of predicted times to ensure smooth racing.
After completing the swim, participants head to a grass transition area before tackling the bike course on smooth grass, looping around the playing fields — 2km laps for most categories, with a shorter 800m distance for TriStart competitors.
The final run follows a 600m tarmac loop around the tennis courts, finishing back on the playing fields where every participant is cheered over the line and receives their medal, water and goodies.
