Dorney Lake Christmas Half Marathon 2022

December 10, 2022


Dorney Lake Christmas Half Marathon

Set at the spectacular, flat, and smooth-surfaced Dorney Lake near Windsor, this Christmas Half Marathon event takes you around the perimeter of the iconic water.

The legendary Eton Dorney – as Dorney Lake was known during London 2012 – held 30 events throughout the Olympics, with Team GB taking a total of 12 medals. Soak up the atmosphere and invoke their heroics to inspire you to a new PB!

The Dorney Lake course is nestled amongst 450 acres of glorious parkland – including an Arboretum and Nature Conservation area – whilst being just a few miles from Windsor and a short drive from Heathrow airport and West London.

Event merchandise is available for purchase during registration for delivery by the following weekend when ordered by Sunday.

All of our events are organised following government and governing body COVID-19 guidance. We will continue to ensure that we deliver safe and enjoyable events.

Entry on the day will be subject to availability and a £5 surcharge.
