Honoring 50 Years of Women at the Boston Marathon

Fifty years ago, Hopkinton, Massachusetts, offered more than a starting line - it launched a movement.

"My biggest fear was that I'd be stopped. I wouldn't be able to prove what I'd come to prove," said Bobbi Gibb, the first female Boston Marathon runner. "I found a little clump of bushes and the gun went off. I waited till half the pack left and I jumped in."
