Nicole, you cannot imagine, how much I understand your awful situation. I myself do not roller blade (74 years), but nevertheless I could add a whole novel to similar happenings. I don't have pepperspray and no weapon (not allowed here). People here are very often angry because of the many strays here (which by the way they produce themselves - no castration etc).
But the strays normally are used to other dogs and are not territorial, so they might be curious, they might also chase a bycicle, moto or I guess a roller bladler,( we don't have here because of the awful streets full of holes), they bark, but don't attack. At least within 5 years I´ve never experienced this.
But ~yes - there are quite a lot of owners who don't care in the least about what their dogs are doing. I had recently an attack from a bulldog who lives behind a sloppily constructed barricade. He always behaves like mad when I pass there with one of my dogs (always on a leash). He succeeded to break through and attacked my Lab-Mix.
I yelled at him and fortunately the owner was nearby and came running to hold his dog back. Mostly he is not there, as the house is in construction, only the dog lives there alone and is of course frustrated, when someone passes by.
I don't know, what would have had happened, if one of my Pits had been with me. They don´t attack humans nor other dogs outside their territory or when we are nearby. But in a situation of self defense?????
I then shouted at the owner, if he was crazy for being so extremly careless and leaving a really aggressive dog behind such a ridiculous fence. He ownly shrugged his shoulders and said, that such things can always happen.
I could continue with such examples. They want to have what they call a protection dog, but don't care that such a dog should be safely locked away.
Now, I already know that some webboard users cannot imagine how negligent some owners can be and would recommend you to avoid this road. In my case, I could do this, yes, easily. I would simply have to turn into the next road and would have to pass by a house, where the next sloppy idiot doesn't care, what his "protection"dog does.
I'm so sorry, I cannot really give you an advise, if you live in such a region as I. Safest way - stay at home! Crazy. I'd never imprison myself and my dogs.
I threatened those people I'd call the police next time. Perhaps in your country exists something like that. Here not. More exactly: they don't engage enough policemen, so the whole thing is worth nothing at all.
IMO, you don't need to feel resentful for roller blading. If you have the possibility to impeach such owners, do it for heaven's sake. they don't learn anything at all, if they don't get a clear and tough answer from above.
Don't hesitate to use your pepperspray!
