The Grim Reaper is back and he’s coming for you! This multi-distance event at the stunning Grimsthorpe Castle Estate in South Lincolnshire gives runners the option of four solo distances - 10, 40, 70 & 100-miles with a 40-mile and 100-mile team option too. There will be two 10-mile races, one in the morning and a night run.
The full marked route is a 10-mile loop that covers beautiful grass trails through ancient woodland, limestone tracks, quiet estate roads and a stretch along a discussed Victorian railway line. It also skirts around the picturesque estate lake before reaching the start/finish point in front of the castle itself.
Whilst there will be a 5-mile aid station, this is a self-sufficient race with an area at the start/finish point to leave tents/supplies to access after each lap.
The three ultra-distances (40, 70 & 100-miles) have a strict cut-off time of 28-hours with a mandatory kit list for the ultra-distances. See Bog Dog website for further details.
Entry includes the the option to camp on the Friday and Saturday nights for FREE.
Trophies will be awarded to the first, second and third male & female in all solo races. Plus, all members of the winning teams.
Grimsthorpe Castle is located near the town of Bourne in South Lincolnshire. PE10 0LY.
