When the pain comes, you know what I do? I smile.

You don't play triathlon. You play soccer it's fun. You play baseball. Triathlon is work that you can leave you crumpled in a heap, puking on the roadside. It's the physical brutality of climbing Mount Everest without the great view from the top of the world. What kind of person keeps coming back for more of that?

Success in the sport is, above all else, about enduring suffering.
