5k-20k-5k of pure fun!

The GRIM Duathlon is one of the toughest short-course duathlons in the country, but we know you’re up for the challenge.

Take on the trails, hills, mud, water, cammo nets, moguls and the sand dune on the Army’s vehicle testing circuit. All the elements are there to be mastered, but this land is more suited to Land Rovers and tanks. All you’ll have will be your trainers, the bike and your willpower. Will you survive?

Enter as an individual or in teams of three competitors over a distance that will seem much longer than it appears. The runs are 5k, the bike, 20k. It’s tough but then so are you – right?

It’s also a lot of fun. The majority of the competitors are game for a challenge and by no means professionals so why not give it a go? It’s a great event for all; a great challenge for beginner to pro. Hope to see you for some GRIM fun.
