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.

There will be hot food and hot/cold drinks available to purchase throughout the event (from 6am on Saturday until 10am on Sunday).

The three ultra-distances (40, 70 & 100-miles) have a strict cut-off time of 26-hours with a mandatory kit list for the ultra-distances. See Bog Dog website for further details (Race section to go live by the end of December ’21).

Entry includes a finisher’s medal, t-shirt and goody bag. Entry also includes the option to camp on the Friday and Saturday nights.

Trophies will be awarded to the 1st male & female in all solo races.

Those who complete the 40, 70 and 100-mile solo races get presented with a special finishers t-shirt.

Grimsthorpe Castle is located near the town of Bourne in South Lincolnshire. PE10 0LY.
