About Glenn Cunningham (runner)
Glenn Vernice Cunningham was an American middle-distance runner, and was considered the greatest American miler of all time. He received the James E. Sullivan Award as the top amateur athlete in the United States in 1933. Cunningham won the Sullivan medal in 1933 for his achievements in middle-distance running. In 1934, he set the world record for the mile run at 4:06.8, which stood for three years. This time was not accepted as a world record, however, because Dartmouth had provided Cunningham pacing runners, which was against the rules at the time.
