Sometime when I was young, maybe in the mid-1970s, I saw this video. Few stories have inspired me as much -- both as a runner, and as a person. He ran the marathon for Tanzania in the 1968 Mexico City Olympics. Famously, he explained why, though battered, bleeding, and broken, he finished a grueling race in last place, "My country did not send me 5000 miles to start the race. They sent me 5000 miles to finish the race."
