Trinity Triathlon was founded in 2012, building on the legacy of the Olympic Games and getting more young people involved in sport.

The Triathlon is one of the biggest of its kind in the UK, and a real community occasion, with around 400 girls and boys aged 6-19 taking part each year.

We work with over 100 volunteers from the School community, Transport for London and Crystal Palace Triathlon Club to ensure the event is a great success.

It is a non-profit making Triathlon, now in it’s eighth year it was set up by the school to create our very own Olympic legacy event.

The Triathlon has been named London Region Children’s Triathlon of the Year for three consecutive years.

This year’s Triathlon is on Sunday 1 July 2018.  Please note that registrations have now closed as the event is fully subscribed.
