Jack Laurence

Yeah, big cash there.

Being the adventurous bloke he was when he travelled north in Australia, he got himself work on a dive boat, first as a volunteer.

But taking advantage of the opportunity, he quickly got himself up to speed with his diving.

He got qualified as a dive instructor and then spent the next year enjoying the clear blue waters and beautiful sunshine that North Queensland had to offer.

Until eventually, it was time to head home and find himself a career.

And again, his thirst for adventure and something a little more fast-paced would lead him to a career in policing.

After a few years working in the police, Jamie felt drawn again to do more exploring.

The backpacking had given him a taste for more adventure, and so he takes a sabbatical from the police and heads off overseas yet again to work as a diving instructor.

While at university, Jamie found himself at the Freshers' Fair.

It's that chaotic first week marketplace where clubs and societies, student groups all compete for your attention and your signature on a sign-up sheet.

And as he's walking around taking it all in, he sees a man in an army uniform with a big handlebar moustache pointing straight at him.

And that was it.

In many ways, it was everything he'd been looking for.

Something where he could get his hands dirty, achieve, push himself, and come away feeling accomplished.

And so he threw himself into it.

Feet first.

Now, to understand the kind of person Jamie was becoming, you need to understand what the Cambrian Patrol is.

It's an annual military exercise run by the British Army, widely considered the toughest patrolling test in NATO.

Eight-person teams are dropped into the rugged mountains of mid Wales and have just 48 hours to cover roughly 40 miles of some of the most punishing terrain on earth, carrying up to 70 pounds of kit on their backs.

To give you some idea of what sort of conditions they're dealing with, Wales is the training ground for the famed SAS.
