The origins of this event can be traced back to 2003, and there's good reason for why participants keep coming back to this cracker of a day out. You'll slip and scramble your way through a variety of fun natural obstacles over an action-packed 4 or 8-mile course. Enjoy a custom finishers medal too.

The GRIM is one of the original muddy/trail/obstacle races with a history that dates back to 2003. After a COVID absence in 2020 it bounced back strongly in 2021 with more than 1000 runners taking part in the event.
It returns in 2022 in much the same format: the route takes you over an Army vehicle testing ground in Aldershot with two distance options, a main race 8-miler and a lighter version over a shorter 4-mile course.
Although the GRIM is a tough trail race in which you will certainly find yourself at times cold, wet and dirty, it is not an obstacle race, it's a running event. We don't build any ramps, walls or swings on the course.
All the obstacles are natural, formed by tanks driving over the route or by incessant rain in the weeks leading up to the event. Of course at this stage, we can't guarantee the rain but it's never let us down before. In a few places you will be crawling under cargo nets or wading through waist high water.
The distance may not sound daunting but don't take this lightly, on a cold December morning, the GRIM is a challenge and you will think it is aptly named when you have run it.

Did the race in 2021
Absolutely brilliant day and thoroughly enjoyed the course. Marshals were excellent and friendly and the course as always a good challenge this is my third year doing this and will 100% be back next year. Goodie bag at the end was a great bonus too! Only one small negative is the medal is the same as I got previously would of liked the date on the ribbon so I could know the difference.

Communication was fantastic throughout! The Grim was fun and everyone seemed to love it. We'll be back. The medal and freebies at the end were a fantastic surprise glad that was included.

Did the race in 2021
Pretty awful, I mean it’s been 24 hours and no results have been posted yet! Most marathons with 15000 people have the results almost instantaneously. Course wasn’t exactly an obstacle course. It had one net on an 8 mile route. Where was the actual obstacles? Pretty abysmal
