You gave three *warnings* in MCP and she still didn't hear you?
Then elbow past.
I don't run in places with many humans, but when I do, like at MCP, I try and call out a "good morning" a good ways away, so I don't scare them. If I notice a human with a dog, I try to immediately get everyone's attention, especially the dog.
I've run with music/podcasts in MCP. It is probably not the best option,for a female. I will say that.
But once you've given the runner the notice, more than once, then go. If it scares/bothers them, it should.
