One thing I know for sure: it is only by doing what we fear that we can ever truly learn to be brave.

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!

Some of the greatest survivors have been women. Look at the courage so many women have shown after surviving earthquakes in the rubble for days on end.

My Christian faith is my backbone

Survival is not about being fearless. It's about making a decision, getting on and doing it, because I want to see my kids again, or whatever the reason might be.

As for my diet, I try to eat lean, clean and healthy - nothing too surprising. And I avoid too much meat or dairy because they slow you down.

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