Join us for the Dorney Lake Duathlon on Sunday 8th March 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.

Each kilometre is accurately marked with distance flags and our friendly marshals will guide and cheer you all the way to the finish. We cannot wait to welcome you to Dorney Lake.
With RunThrough you can expect a friendly team of marshals to help guide you round the course and cheer you on to the finish, a lively and well-serviced event village with plenty of food and drink options including free goodies from our partners at the finish line after your hard effort.
We have been extensively researching what runners consider important, and sustainability is fast becoming the top issue. Click here to see what RunThrough is doing for sustainability.
You can now grab your Dorney Lake event t-shirt for more than 30% off when you buy it as part of your entry on checkout! With the event logo printed on the chest, it’s the perfect keepsake to celebrate your race and wear your achievement with pride!
We can do this with our partner RT Kit as part of a strategic decision to raise awareness about the quality of the product whilst reducing the overall cost of events for those who would prefer not to have a t-shirt included.
Come and enjoy the day with us. Once you enter you will receive a confirmation email. More information will be sent closer to the event.
We can’t wait to see you on the start line!
