The Krypton Factor’s very own obstacle race is back – The ADRENALIN SHOCK – new routes and new obstacles!

This is a unique obstacle course race featuring the KRYPTON FACTOR assault course, as seen on TV & film, the most famous, and arguably, the hardest assault course in the UK.

A choice of 5km (min 37 obstacles) and 10km (min 52 obstacles). Off road routes that include marsh, bog, woodland, rough hilly ground interspersed with tracks and fields, and a arduous river run, and if that was not enough, at the end you will encounter 800 metres of deep mud and water between 24 plus obstacles to negotiate en route to the finish.

The obstacles are evenly, tightly spread around the course. They are large and over half have more than one component to them, to climb, jump, wade, swing and crawl over and under. It will seem endless and you will need to dig deep and muster every bit of stamina to maintain your pace and position. The harder you push yourself, the more intense it will become and relief will only come when you cross the famous double Ks finish line of the Krypton factor.

Entry fee is £30 per entrant for the 10km course, or £20 per entrant for the 5km course. Teams are welcome. Be aware that there are a limited number of places for this race!

ABF The Soldiers’ Charity has proudly partnered with Adrenalin North Yorkshire Ltd for many years and all participants are encouraged to support the charity by fundraising.
