About this event

📅 26th September 2026
📍Dorney Lake, Windsor
👣 Triathlon

Prefer swimming and cycling? The Dorney Lake Triathlon Sprint Aquabike combines two disciplines into one exciting challenge, giving you the chance to swim and cycle your way to the finish.

This race is a brilliant alternative to a traditional triathlon, focusing on two disciplines: swimming and cycling. It’s a great challenge for athletes who enjoy the water and the bike but would rather leave the running shoes at home.

It consists of a 50m open-water swim and a flat 19km road bike course at the historic London 2012 Olympic venue in Windsor.

Combining endurance, speed and determination, the aquabike format gives you the opportunity to test yourself across two demanding disciplines. Whether you’re an experienced multi-sport athlete or simply looking for a different kind of challenge, it’s a fantastic event to add to your goals
