About this event

📅 13th June 2027
📍Alexandra Gardens, Windsor
👣 Triathlon

The Royal Windsor Triathlon Sprint Relay is a brilliant team challenge, giving you the chance to experience the excitement of triathlon while sharing the three disciplines with your teammates.

Make up your team of 2 or 3 people and split the disciplines: a 750m River Thames open-water swim, a 22km open-road countryside cycle, and a 5km run along the historic Long Walk.

Divide the challenge between your swimmers, cyclists and runners, encourage each other along the way and work together to reach the finish line. Whether you’re entering with friends, family or colleagues, the relay format makes completing a triathlon accessible, social and incredibly rewarding.

Set against the backdrop of Windsor, this is a fantastic opportunity to turn a sporting challenge into a memorable team experience.
