A new report shows how much harassment female joggers experience while on a run.
According to a Runner's World report titled "Running while Female," 58 percent of female runners under the age of 30 say they are harassed while running. In most cases, the harassment is sexual.
The report also shows one in three female runners say they have been followed by someone in a car, on a bike or on foot.
Researchers hope the survey will help men realize how widespread the problem of is and put an end to it.
