I've seen extreme bravery from the least likely of people. Life is about the moments when it's all gone wrong. That's when we define ourselves.

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

My faith isn't very churchy, it's a pretty personal, intimate thing and has been a huge source of strength in moments of life and death.

To get ready to climb Everest, I did a lot of hill running with a daypack on and a lot of underwater swimming. I would swim a couple of lengths underwater and then a couple above. It gets your body going with limited oxygen.

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.

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