There is little faith involved in setting out on a journey where the destination is certain and every step in between has been mapped in detail. Bravery, trust, is about leaving camp in the dark, when we do not know the route ahead and cannot be certain we will ever return.

There's no magic to running far or climbing Everest. Endurance is mental strength. It's all about heart.

I've never really had a TV career. I've been a soldier and a climber.

The truth is, I need 10 lifetimes to scratch the surface of the things I'd love to do.

The hardest thing about my job isn't the snake bites or the crocodiles, it's being away from my children. I have a really religious satellite phone call every day back to the boys, wherever we are, whatever time zone, to say goodnight.

Alpha was the best thing I ever did. It helped answer some huge questions and to find a simple empowering faith in my life.

It's unresolved conflict in my life that I have a lovely family and a risky job.
