When it comes down to it, it’s pretty simple. Adventure is what you make it. And whether it’s the travel, the discovery or just the feeling of letting go, the only way we’ll ever find out is to get out there and do it. Enjoy the ride.

Being out on the ocean seems like a different world to being in the mountains and the backcountry, but there is also a lot of symmetry. They each have their own biorhythms from a motherly embrace to tempestuous wrath. What I love about being out in nature is that you are at the mercy of your own decision making.

Apart from those other riders there is a whole production team [ of The Fourth Phase] behind the cameras too, hauling hundreds of kilos of fragile and awkward filming equipment up those same frozen landscapes. They're the real heroes.

One of the proudest things for me with this film [The Fourth Phase] is that year after year we put ourselves right out there making it and no one got seriously injured.

They were all just chapters in the book, stepping stones. Each was perfect for where we were at the time, and I'm proud of them all. We couldn't have done this film [The Fourth Phase] without the other films pre-dating it and being part of the process.

I find I enjoy myself most on those days when it's just me and a couple close friends away from it all. True human interaction in a day when we are all spread so thin.

We faced blizzards, sub-zero temperatures, and of course dangerous snow conditions and vertiginous drops. That's what you get when you're working with fickle mother nature - you start out with a solid plan and it always changes, so you have to evolve and adapt.
