Happens to me quite a lot. The village I live in is nice and quiet but our running club meets up and runs through a smallish town nearby, and it's a bit of a rough area. We often get shouted at by old guys standing outside pubs smoking. Usually nothing offensive and often compliments and encouragement. We also get shouted at by young chavs and they tend to be less friendly. A few times we've been targeted by boy racers in silly cars who have driven past us up to a dozen times, leaning out the window and shouting each time they go past. They're usually leering at the younger women wearing shorts. And on the bike paths we often have to run through gangs of lads hanging about drinking Mad Dog and Buckfast. With them I find if you smile and say hi as you go past they're usually friendly, but if you run past with your nose in the air they will often be offensive just for the sake of it. I've never felt threatened or in danger while out running, even on my own in the dark through gangs of half pissed chavs. I'm fairly sure I could outrun them no bother...
