In the British Special Air Service, combat fitness is all about running.

I never wanted to do TV. I just did what I was trained to do through the Special Forces, and I've been doing that from a very young age.

The special forces gave me the self-confidence to do some extraordinary things in my life. Climbing Everest then cemented my belief in myself.

I think it's fun running with dogs. They're always so fit and fast.

Christianity is not about religion. It's about faith, about being held, about being forgiven. It's about finding joy and finding home.

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.
