GRIM is held over the Army’s vehicle testing tracks so expect it to be interesting! You encounter a trails, hills, mud, a lot of water, moguls, a sand dune, logs, railway tracks, cammo nets and a bog! Whats not to like?

It’s tough but we know you wouldn’t want it any other way!

The course is approximately 8 miles long. It changes depending what the army are doing & how mean we’re feeling. Besides, you get a breather wading though the puddles (we’re kind like that) so it can’t be too hard – right?

Either enter as an individual or round up some mates and enter as a team of three people in either the women only, men only or mixed team categories.

There are prizes for the top 5 individuals and the winning teams.

Entries close when we sell out – and we will, so don’t delay.



  • Early bird entry is £27 up until February 28th, 2015
  • Standard entry is £31 from March 1st, 2015
  • Late entries are £35 from November 1st 2015
All entries subject to £2 entry system fee


We’re sure you are tough enough – see you on the start line!
