I ran in the dark. For part of the time a guy on a bike was following me. It's possible that he and I were just on the same path coincidentally, but it was a little creepy, since he had ample opportunity to pass me. I was totally primed to fight.
Then I was about a quarter mile from home, really wanted to add on some so I could get to 3 instead of 2.5, but not with some creep following me. So I sneaked a peek behind me only to discover he wasn't behind me anymore. So he probably wasn't behind me for as long as I thought he was.
I got my 3 after all.
