I was lying to myself and didn’t even realize it. After completing numerous 5K and 10K runs, I was considering taking my running to the next level by training for my first half marathon. I would visit the specialty running store and look longingly at the glass case of GPS smart watches. “If I only had one, I’d run more,” I’d say to myself. “I would have up-to-the-second data and an increased desire to run. Everything would be easier.” I took the plunge and made the purchase. The features were helpful, and for the first few days, I did get excited to take my watch out for a spin. But over time, did it make me run more or was it essential to my running? Not at all.
