The Event

Taking place at the stunning Marlborough College in Wiltshire, young participants will take on a swim, cycle and run, with distances designed to be achievable for a wide range of abilities. The focus is on having fun, being active and enjoying the sense of achievement that comes from completing all three disciplines.

The event takes place within the grounds of Marlborough College, with a pool swim and safe grass cycle and run courses. Friendly marshals will be on hand throughout the event to guide and encourage participants, helping make the experience enjoyable and reassuring for both children and parents.

Every child who completes the event will receive an official Kids Fun Triathlon finisher’s medal, presented on the finish line. It’s a fantastic opportunity to try something new, challenge themselves and create a sporting memory they can be proud of.

Race Day Information

Competitor race day information and your individual start time will be emailed to you 7-10 days before the event from UK Triathlon.

Please check spam/junk folders.

Fundraising

Fundraising is completed before the event via your fundraising page. This is automatically created for you when filling in the entry form. It can easily be shared with family, friends, or anyone to help raise fundraising donations online. 

Secure your place now and start your fundraising whenever you like.

By signing up to the UK Schools Charity Triathlon, each competitor commits to a minimum fundraising target of £50 to take part, with an ideal goal of £100, split between your school and chosen charity.

Teams

A team can consist of two or more members.

All team members must use the same team name and sign up for the same distance.

Teams are simply a way for children to take part alongside their friends. Each team member completes the full triathlon themselves. They’ll start one after another at 15‑second intervals from the swimming pool, and they’re welcome to cycle and run together, finishing as a group if they’d like.

Every child will still receive their own individual overall time.
