GRIM Original started in 2002, was one of the original mud runs and is now one of the largest in the country. Now a teenager, the event still has serious 8 miles of attitude so if you’ve never run it before, we’d love to welcome you to Aldershot.

Held on the Army’s vehicle testing tracks, you’ll need to tackle a wide range of terrain from dirt tracks to stony paths to muddy puddle-strewn paths, a bog… Expect the unexpected!

This year we’ve launched 2 new events at our big December GRIMday. For those who feel that they might not be able to take on the whole challenge, we’ve launched a half-distance 4 mile event incorporating some great parts of the longer distance course. It’s shorter but relentlessly GRIM. As it is shorter, we’ve also been able to lower the age limit of this event to 13 so our tough / mad kids can give it a go.

For those ultra-tough GRIM nutters, we’ve launched a 2-lap 16 mile event which truly lives up to it’s GRIM X name. For those who like to go long, we salute you.

You can enter as an individual or enter with some mad friends, there’s safety in numbers… There are three team categories: men only, women only or mixed teams and all teams must be made up of three people.

FAQs
WHAT IS THE AGE LIMIT?

Runners must be aged 13 or over to enter the Short Course 4 mile course. Runners must be 16 or over to enter the 8 miles and 16 miles courses. The course is much harder than a normal cross-country course so 16 seems to be a sensible age limit to us.

FOOTWEAR

Your shoes will get wet and muddy so best not wear a brand-new white pair! No Spikes – most of the paths are too stony for them and too dangerous for other competitors when crawling under netting! Shoes with a very good grip are ideal. We recommend taking advice from Shoeguide.run. They review the lastest running shoes on the market and offer advice on the best running shoes for your running style. You can even buy through them also as they shoe the lowest prices
