Those men are absolute shitbags, but please, please do not let them win.
I was way, way overweight when I took up running - I weighed more than you do, and I'm only 5'3". I was so, so painfully self-conscious about it, almost to the point of being phobic, but I forced myself to persevere and it was the best thing I ever did.
If some awful bloke shouts something at you while you're running, it honestly has nothing to do with your weight - I don't think I ever had anyone shout anything at me when I was actually fat, in fact, but I did have someone shout 'fat cow' at me when I was a size 12. Some men basically just can't handle the idea that women are fit and confident. You were out there running, and they were not, and that is essentially what their issue is. They're insecure and threatened, the sad little wankers.
Once I was just finishing up a run and had reached my distance and was walking the last 500 metres or so as a cool-down, and moments after I'd slowed down and looked at my watch, some absolute bellend walked past with his mate and said 'Oi, sweaty' at me (I sweat buckets when I run, which I hate). I was so high on endorphins that I turned around and said 'I've just run 5 miles. What have you done today, you lazy c**t?' And his mate told him he deserved it
