I will say, as a woman, when you are alone (either running, cycling, walking down the street, sitting in a restaurant, riding the bus, you name it), a part of you is constantly on high-alert for potential harassment. Always. It's exhausting, but unfortunately just the way it is. This is partially why you often see groups of women doing activities together - biking, running, etc. There is safety in numbers.
I will say that there is something about a woman on a bicycle that infuriates certain men. I'm not sure what it is, but evidently this has always been a thing (and is also addressed in the podcast):
