Maureen Wilton Mancuso, who broke the world marathon record at age 13, received few accolades but much criticism

Maureen Wilton Mancuso was just 4-foot-10 and about 80 pounds, but she was all heart, lungs and legs. When the little Canadian girl ran her first marathon in 1967 at the age of 13, she broke the world record. Today, her feat would be reported and celebrated across the globe. But 45 years ago -- when women were discouraged from running long-distance races -- her accomplishment was largely ignored or simply dismissed as a strange occurrence. "It's like pushing peanuts up a hill with your nose," said one Canadian track official. "She did it, but so what?"
