The new direction for the Grim Reaper
The Grim Reaper was relaunched in 2023 by Steve Cole & Laura Bailey, runners local to the Grimsthorpe Estate who compete in races of distances from 10km up to 100-miles. Their plan was to create an event that catered for runners of all abilities, in a stunning location and with a friendly, supportive vibe. It's fair to say that the 320+ runners in 2025 feel they achieved that goal judging by the 4.9* (out of 5) rating on Letsdothis.com
Located at the beautiful Grimsthorpe Castle
The route is a 10-mile loop that covers beautiful grass trails through ancient woodland, limestone tracks, quiet estate roads and a stretch along a disused Victorian railway line. It also skirts around the picturesque estate lake before reaching the start/finish point in front of the castle itself. We class this as an ‘undulating’ trail course with no major hills to contend with, making it ideal for those new to ultra-running, looking to take the next step to a longer distance or aiming for a PB. The course will be fully marked.
