The Grim Reaper
The Grim Reaper is back for 2026…and he’s coming for you!
Runners have the option of four solo distances – 10, 40, 70 & 100-miles – plus 40-mile and 100-mile team relay options. There will be two 10-mile races, one in the morning and a night version.
Expect a mix of estate roads, limestone tracks and grass trail. Trail shoes are recommended, especially in damp/wet conditions.
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.
