I often hear someone say, "I'm not a real runner." We are ALL runners, some just run faster than others. I never met a fake runner. As long as you push yourself every time you get out there you're a runner!
So you had a bad day. Dont beat yourself up over it, but dont let one bad decision send you spiraling out of control. Grab those running shoes and get back into it. Get back into making decisions that improve your health and happiness. You are who you
It's very hard in the beginning to understand that the whole idea is not to beat the other runners. Eventually you learn that the competition is against the little voice inside your head that wants you to quit.
