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.

There is magic in misery. Just ask any runner.

I love to run and I have some tips to keep it fresh and novel. I rarely use the same route twice. That keeps things new.

I've raced on all seven continents at least twice. I've probably run thousands of races. But the single race that I'm most proud is a 10K. Yes, a 10K. I ran it with my daughter on her 10th birthday.

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

Regardless of how distant your dreams may seem, every second counts.

People think I'm crazy to put myself through such torture, though I would argue otherwise. Somewhere along the line we seem to have confused comfort with happiness... Dostoyevsky had it right: 'Suffering is the sole origin of consciousness.' Never are my senses more engaged than when the pain sets in. There is a magic in misery. Just ask any runner.
