I love surfing, rock climbing, cycling - all that stuff. But it's just amazing that I can inspire people with my running. It's humbling, really.

I run to breathe the fresh air. I run to explore. I run to escape the ordinary.

If someone had said to me before I started doing this that a human being is capable of running 100 miles nonstop, I would have just said: 'No way. I mean, how?' If you just go out there and run 100 miles, it breaks down a lot of barriers in terms of self-imposed limitations.

I have an ElliptiGO. It's a standup bicycle. You don't pedal; you stride on it. It allows me to have the same striding motion as running without the impact.

A Marathon is not about running, it is about salvation. We spend so much of our lives doubting ourselves, thinking we're not good enough, not strong enough, not made of the right stuff. The Marathon is an opportunity for redemption. "Opportunity," because the outcome is uncertain. "Opportunity," because it is up to you, and only you, to make it happen; only you can turn your farfetched dream into a reality.

I have my whole office set-up at waist level; I don't sit at all during the day. Sitting, to me, is the devil.

Some seek the comfort of their therapist's office, other head to the corner pub and dive into a pint, but I chose running as my therapy.
