Dorney Lake Duathlon November 2026

Join us for the Dorney Lake Duathlon on Sunday 8th November 2026

Take on a Sprint or Standard distance and take the opportunity to race around this unique and inspiring Olympic venue!!

The flat and scenic grounds lend themselves to a totally flat bike and run course, the ideal venue for a chip-timed personal best. Each discipline will be accurately marked out with distance flags and we will have plenty of helpers to keep you on track and to encourage you all the way to the finish.

For those who would like to compete as a team, there is a relay option, which allows 2 or 3 individuals to share the disciplines between them.

This is a partner event. RunThrough memberships can be used for entry; however, once the event sells out, no additional places will be available, including for members. Please note there will be no RunThrough member desk, and member bibs cannot be used at this event.

With RunThrough, you can expect a lively event village and clear guidance from our on-course team. After your run, enjoy food, drink and free finish-line goodies from our partners.

You can add an official event t-shirt to your entry at checkout for more than 30% off. Produced in partnership with RT Kit, it features the event logo on the chest and is the perfect keepsake to celebrate your race. Offering the t-shirt as an optional extra helps us keep entry costs lower for runners who prefer not to include merchandise.

Once you enter, you’ll receive a confirmation email straight away, and full event information will be sent to you closer to race day.

We look forward to seeing you on the start line.
