Born Survivor's not your average trail run or obstacle event. It's designed to be tough and testing and it may just break you. You'll need to be physically fit and mentally prepared to cope with the challenges and endure the suffering. Expect mud, expect hills, expect water, but don't expect gimmicks; this course is the sort of challenge the British Army face in their training every day.

Your mission, should you choose to accept it, is to push yourself to the limit tackling the ultimate military obstacle course designed by British Royal Marines Commandos. You'll be put through your paces as you stampede over, under and through a series of military style obstacles across either a 10km or marathon course of brutal and unforgiving terrain.

If you dare take on this adventure you'll need to be prepared to display courage, determination and a stiff upper lip to conquer the challenge. We encourage teamwork and even if you don't enter as a team we know you'll assist your fellow Survivors in completing the course. Never leave a Soldier behind, it's the British Army way and it's the Born Survivor way.

If you think one 10km lap will be too easy, think again, but if you really think you've got what it takes to join a special elite group, why not take on the Born Survivor Marathon?
