The story of Cliff Young has always fascinated me. If you have not heard of Cliff Young then let me tell you a story of how a 61-year-old farmer turned the professional running world upside-down.

In 1983, Australia hosted its ultramarathon, a 573.7-mile foot race from Sydney to Melbourne. This is a race that takes days to run, and professionals from all over the world came to participate. Shortly before the race began, a 61-year-old farmer named Cliff Young, wearing overalls and galoshes over his boots, walked up to the registration table and requested a number to enter the race. The people at the registration table thought it was a joke—that somebody was setting them up—so they laughed. But Cliff Young said, "No, I'd really like to run." So, they gave him a number and pinned it on his old overalls.
