Just picked up a new pair of running shoes now that I'm back into running. The salesperson at the fancy running store seemed surprised that I don't use an app or some kind of tracker. Why would I need to? I'm not competing. I just want to stay fit. My competition is myself and my goal is to run until I'm satisfied with my workout. Why would I care if I ran X number of miles or what my speed was? How does that help me? It seems like a distraction with no point other than showing off to other people. I used to track my hiking miles back in the day. All it did was justify poor eating habits or give me a false sense of pride.
