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

The GRIM Duathlon is a tough short-course duathlon – and it’s new venue was totally awesome!

The course is great. Just off junction 4a from the M3,  competitors will need to take on the army’s trails, hills, mud, water and cammo nets to complete the course. All the elements are there to be mastered and it will certainly provide a test for man and machine.

The route is really scenic and undulating which makes for a for a great ride. The run was tough – and we made it tougher!

Enter as an individual or round up some gutsy mates and enter as a team of three. The runs are 5k, the bike, 20k. It’s tough but then so are you – right?

Like all GRIM events, it’ll also a lot of fun. We get the hard-core at the front but 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 on the start line.

Our official charity partner for GRIM Duathlon is Macmillan Cancer Support, helping people live with cancer. We are delighted that they are supporting us and we hope you’ll support them by raising a little sponsorship for your effort.
