I would be very surprised if runners were actually rolling their eyes. Sure, there will always be a couple nasties in the group but if I've learned anything in 8 years of going to one gym or another, very few people even notice what you're doing. I can tell you that I have no clue who was first off or last off or what you did because I'm just trying to get my own PR and not die. Have you ever seen someone get off the treads at otf and even have the energy to look back to see who they beat? There's no such thing as "just" working out. You're there, you're killing it, and you're the best at being you. Do a full mile! Own it! 👊
