About | Kernow Killer

Bought to you by Cornwall Sports Events; an assault course designed to use the tough Cornish landscape to push you to your limits.

A lot of people run to see who is the fastest. At the Kernow Killer it’s to see who has the most guts, and can punish themselves into exhaustion.

Nestled within 400 acres of woodland, farmland and parkland. The Kernow Killer is situated within the stunning Chyverton Park Country Estate.

Two courses:

1) Kernow Killer: 9-10 miles; 1 lap; 50+ obstacles; Saturday 30th October 2021
2) Kernow Destroyer: 4-5 miles; 1 lap; 25+ obstacles; Saturday 30th October 2021

All courses are gruelling and dependent on your mental state differing in distances; you will be faced with obstacles to climb, scramble through, wade across, swim either over or under; any means may be necessary. These obstacles will use the challenging natural landscape to push boundaries, and we have built man made obstacles to really sort the men from the boys!

These gruelling miles will test your physical and mental strength and will bring a new meaning to the word ‘pain’. At Kernow Killer we believe there is one thought that can help you through these miles:


Once you reach the finishing line there will be a licensed bar where you can party the night away and FREE camping!!

You can contact us with your preferred start time and we will try our best to accommodate this.
