The Schools Triathlon Series is back for 2025!

Each year the global not-for-profit charity Restless Development hosts the award winning Knight Frank Schools Triathlon - the UK’s largest sport fundraising event for children.

This year will be the biggest year yet with nearly 11,000 pupils from over 200 schools across the UK coming together to raise over 1.3 million pounds for Restless Development and more than a hundred of other charities. The vision remains for this to become the London Marathon for children and each year they get closer to achieving this goal.

The Knight Frank Schools Triathlon is an annual series of events that encourages children of all abilities to participate in a day of swimming, running and cycling as a team. Over 200 schools across the country use the event to build confidence in children by building their fundraising skills and sporting abilities. The events take place on Sundays in the first half of the summer term and are run by Restless Development as the organising charity with support from hundreds of local volunteers. 12 triathlons are set to take place around the UK over weekends in May and June hosted by the UK's leading schools.

The Schools Triathlon captures the determination, power and compassion of young people as well as the local community coming together to support fantastic causes. Anyone who is interested in volunteering at the event or hosting a triathlon in the future should contact the organisers at schoolstriathlon@restlessdevelopment.org.
