Dean Karnazes Endurance Quotations

Yes, my dad's a marathoner. He used to do sprint distances and then started marathoning. My mom is an endurance animal. She does three-day events like the Susan G. Komen three-day walk.

To an extreme athlete, there's a certain appeal to doing extreme things - seeking the most extreme physical challenges in some of the most extreme climates in the world. Testing and expanding the limits of human endurance is kind of my thing.
