Dorney Duathlon

Sat 4th October 2025

Four runners participate in a race near a building with glass panels and white canopies. The man in a bright green shirt and black shorts leads, smiling, with two men in black shirts and one in gray shirt running closely behind him. Two people are running on a foggy day by a body of water, wearing athletic gear and race numbers. They are smiling, with arms around each other. Other runners are visible in the background, some wearing hats and visible race bibs. A cyclist in a colorful jersey and helmet rides a road bike at high speed on a smooth, paved path. The background is blurred, indicating motion, with greenery and a body of water in the distance.

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.
