OMG THIS! I used to think everyone in the world was staring at me when I ran on the street but I realized 1) I never notice runners and if I do I’m usually preoccupied and don’t care about them because why would I? and 2) people watching you are in their cars driving somewhere, not running, and most likely don’t run or get the exercise they should, so even if they notice you, who cares what they think? Just run!!!
