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

For me, my training is a key part of my work as so often my life has depended on being able to move fast and haul myself up and out of something fast!

A man's pride can be his downfall, and he needs to learn when to turn to others for support and guidance.

If you risk nothing you gain nothing

Are you the sort of person who can turn around when you have nothing left, and find that little bit extra inside you to keep going, or do you sag and wilt with exhaustion? It is a mental game, and it is hard to tell how people will react until they are squeezed.

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

I've had so many injuries in my life that it's ridiculous.
