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

A choice of 5K, min 38 obstacles and 10K, min 53 obstacles. Off road routes that include a 900m river run, marsh, bog, woodland, rough hilly ground interspersed with tracks and fields, and if that was not enough, at the end you will encounter 850m of deep mud and water between 24 plus obstacles to negotiate on 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 K’s finish line of the Krypton factor.

This race is designed to minimise queuing at obstacles and is run by ex parachute regiment soldiers, who know tough.

Adrenalin Shock 10K, is a qualifying race for European & world OCR championships.

The minimum age for the 10K route is 16yrs.

The minimum age for the 5K route is 12yrs (must be accompanied by an adult/guardian).
