Royal Windsor Triathlon
- RunThrough UK June 2025
Join us at The Royal Windsor Triathlon on Sunday 15th June 2025.
Starting with a swim in the River Thames (watch out for swans!), triathletes then ride a bike route that heads through the streets of historic Windsor, passing Windsor Castle, and out into the surrounding countryside. To complete their challenge, participants will then run into Windsor Great Park and along the spectacular Long Walk in the shadow of the iconic castle. A truly ‘royal’ route, and one that will linger in the memory. You can find out more about the route here.
