Walk, Jog, or Run a 50km Ultra or take on the 25km half challenge – and make next Easter weekend one to remember.
Make it an active Easter this 2024 and sign up to the 50km or 25km looped route through, staring from our basecamp in Windsor leading into the Great Park with wonderful views of the historic Windsor Castle on to Runnymede, along the Thames Path, and takes in some wonderful countryside. Walk, jog or run as an individual or a team, with full support and hospitality all the way.
Your entry includes a range of free food &drink at regular rest stops, and support from medics, marshals and massage teams. As you cross the finish line, you’ll get a glass of fizz, t-shirt, and a special medal to celebrate your achievement.
