Flirting or friendly?

There was a group run she was at, the begininnig I saw her and we talked a bit, I apparently sat in her chair so she knocked me for that. She came over to my group after the run and hung for a few , we talked a bit. During the run she ran next to and behind me a few times. I went to say by to her when I left and she made a sad face that she couldn’t make the race on Saturday. She told her friend that I have a very sarcastic sense of humor but the way I heard it sit sounded like she was saying I was psychotic so I teased her for that. .
