2016 will celebrate the 50th year that women have run the Boston Marathon. Now they make up almost half of the racers, but in 1966, Bobbi Gibb tucked her hair into her hoodie and sneaked into the race.
A year after Gibb's first run, Kathrine Switzer registered for the race
using her first initial, but the race co-director Jock Semple chased her onto
the course and tried to pull off her bib number. Men who were racing knocked
him out of the way.
Gibb will serve as grand marshal for this year's race — the 120th.
