In 1980, Rosie Ruiz was crowned the female winner of the Boston Marathon.

But the Cuban runner was not known in marathon circles and her victory instantly raised eyebrows.

Men's champion Bill Rodgers was there when Rosie was crowned at the finish line with laurel leaves.

"I became suspicious of Rosie pretty quickly," he said. "A really fit, strong, marathoner, woman is pretty tough. Rosie was not that fit looking. It's just as simple as that."

Bill tells Vicky Farncombe about the subsequent investigation and how Rosie's story, in an odd way, changed marathons for the better.
