Grim Challenge Original – 8 Mile Muddy Trail Run
GRIM is held over the Army’s vehicle testing tracks so expect it to be interesting! It’s tough but we know you wouldn’t want it any other way and 6,500 nutters in 2010 are proof of that. 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.
