We pretty much had crazy weather, historically speaking, in every location we filmed [The Fourth Phase]. Nothing has been normal in the past three years.

We're all doing what we love. It's how we express ourselves - operating in a space where you don't know if something is possible or not.

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.

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.

When your location is a snowy mountain in the winter the obstacles are pretty extreme.

It's probably the most personal project [The Fourth Phase] I've done, which changed the dynamic a little bit.

I love to snowboard with no cameras: 100 percent.
