Have you got what it takes?

Welcome to the GRIM Series; events for people who want a dirty adventure.

GRIM events are held on a variety of terrains from Army vehicle testing sites and training grounds to UK’s best motocross circuit, so expect the unexpected! GRIM events are designed tough but fun – we know you wouldn’t want it any other way.

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.

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.

The Beast is our ‘short’ trail run event held in May each year – a super tough 10km over rolling countryside with a killer motocross circuit thrown in twice for good measure – you’ve got to see it to believe it and you’ve got to be good to break the hour!

We know you want to come out and play at a GRIM event this year and we’re sure you’ve got what it takes. See you on a start line soon.

Let the filth fun begin!
