Running makes us happier and healthier, and yet it can also make women fear for their lives.

A 2017 report by England Athletics showed that one in three women were harassed while out running, with nearly half of female runners saying they don’t feel safe when out alone.

Running in groups is often suggested as a way of staying safe – but why should we have to? Sadly, a viral Twitter debate on women’s running safety proves just how bad it can be for women who run solo.

A writer asked the question: what kind of protection do you use when you go out running?

Although many of the 800 replies from people around the world might sound shocking at first, they also build a true picture of the lengths women go to feel safe while exercising.
