“As long as my heart's still in it, I'll keep going. If the passion's there, why stop?...There'll likely be a point of diminishing returns, a point where my strength will begin to wane. Until then, I'll just keep plodding onward, putting one foot in front of the other to the best of my ability. Smiling the entire time.”

“I don't know about you, but all this modern technology that's supposed to save us time and effort has actually ended up making things more complicated in my life, eating up extra time.”

“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.”

“Beyond racing, I just love the art form of running, of conceiving new ideas like the 50 Marathons in 50 States in 50 Days. It's the ultimate expression of what I love to do, which is run, and travel, and see this great country.”

“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.”

“There are so many things in life that divide us, that separate us and tear us apart, be it race, religion, creed, socioeconomic level, nationality or any variety of other factors. But running is something that we all share in common.”

“It had been said that the marathon doesn't really begin until mile twenty. I say mile twenty-six would be more appropriate. The final two-tenths of a mile is filled with emotion. No matter how desperately you're struggling at this point, thoughts typically drift away from the immediate task at hand (ie, survival) to broader feelings.”

“Running is about finding your inner peace, and so is a life well lived.”

“Run when you can, walk if you have to, crawl if you must; just never give up.”

“How to run an ultramarathon ? Puff out your chest, put one foot in front of the other, and don't stop till you cross the finish line.”

“As long as my heart's still in it, I'll keep going. If the passion's there, why stop?...There'll likely be a point of diminishing returns, a point where my strength will begin to wane.
