Original GRIM – everyone’s favourite 8 mile off road challenge
GRIM is an 8 mile off-road challenge run on the Army’s vehicle testing track in Aldershot.
You will run on a mixed terrain – trails, rocky paths, sand, mud, hills and through some rather large puddles – expect to get wet.
The event is great fun with people coming back year after year for more Grimness.
It’s open to men and women and you can walk or run the event so you don't have to be super fit!
Why not round up your mates and enter a team for a weekend of mud and mayhem.
Entry is just £23.
