Dorney Lake Duathlon - December

Sat 12th December 2026

Several cyclists wearing helmets and racing gear ride closely together down a shaded, tree-lined road during a competition or group ride on a sunny day. Five runners are celebrating and jumping in the air by a lake. They are wearing race bibs and sports attire. The sky is partly cloudy, and other people are visible in the background. A woman in a red marathon shirt and black leggings runs on a paved path beside a body of water, leading a group of runners. It's a clear day and the landscape is green and open. Two women wearing matching pink "Cousin Run Club" shirts and race bibs joyfully hold hands and smile as they run on a foggy road, surrounded by other runners in the background.

Fantastic event. Absolutely loved the flat tarmac course, and it being traffic free felt really luxurious! The marshalls and officials were all great as well. I'll be back!

Great location as traffic free and flat. Felt that duathlon competitors did not get the best support with portaloos (except for one in transition), as they were well away from transition area. Course is great but the start is a mass start for all events meaning alot of athletes competing for limited space in the first half mile. Would advise slower runners to start nearer the back for a calmer start. Great support from the marshals both directing and supporting.
