Are you up for the challenge?

Follow in the footsteps of  “twelve true knights” who, commanded by King George III, completed the first recorded perambulation of the Dartmoor Forest bounds and in doing so, established one of Britain's oldest long-distance routes.
​
Inspired by this historic journey through one of Britain's last remaining wildernesses, and in partnership with the Dartmoor Outdoor Festival and Dartmoor Search & Rescue, Manumit is excited to announce our first ultra marathon open to anyone who feels the call of the wild.

---

What is it?
​Two routes to choose from. 50 miles or 50 kilometres.

Both trail routes that combine runnable moorland, rugged beauty and proper adventure.
