Event details

Whatever your ability level, there's a distance to suit you: from a challenging 10k to a tough 25km and all the way up to the historic full 50km. You can run as an individual, or bring friends and family to run as a team! 

Starting from Windsor Racecourse, you'll pass through the Great Park and enjoy great views of Windsor Castle, before heading out around Runnymede and along the Thames Path, as well as passing the historic Eton College. All routes will experience some beautiful river and countryside views, and enjoy some of the region's loveliest scenery.

You'll be well-supported with snacks, drinks, and hot meals along the way, as well as medical and welfare support. They'll keep you fit and fuelled all the way to the finish line, where a well-deserved glass of fizz awaits!

How we'll support you

  • We'll send you a free Parkinson's UK breathable running top. 
  • You'll have access to expert training and fundraising advice.
  • We'll send you a welcome pack and fundraising materials.
  • You'll get regular email updates and invitations to our social media groups.
