Your mission, should you choose to accept it, will not be for the feint hearted but will definitely be for those wanting fun.

Come and take on GRIM Blackout – it’ll be as GRIM as ever – we promise!

The course is 7 mile in total set out as 2 x 3.5mile loops. It’ll be dark, it’ll feel long, it might be scary and you’ll need a head torch to keep you safe – be we know you’ll be fine.

Operate outside military protocol and keep your wits about you. During blackout, the woods appear creepy, the hills more hair-raising than ever and the waist high water water might well shock you a little.

But, there’s safety in numbers.

We also know they’ll be a lot of laughs along the way. You can enteras an individual or why not round up other some other brave souls and enter a team in one of our three categories: women only, men only or mixed teams. At the end you can relax at the ComplexCity Spa.

Our official charity partner for GRIM BLACKOUT 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 dark effort.


We know that for the ultimate Grim warrior out there one event is not enough and we’ve had a few requests from people wishing to compete in both the GRIM Blackout and the GRIM Duathlon earlier in the day! So, for the ultimate nutter, we’d like to offer you guys a tenner off.

Enter both and drop us an email to let us know. We’ll refund your card £10 for you to spend at the asylum
