I’m a firm believer in the mantra that what doesn’t get measured doesn’t get done. Did your doctor want you to start running 3-4 days a week? Did you? If you don’t track it, then it probably won’t happen. All that is standing between you and tracking your run is an app download.
If you already use your iPhone while running to listen to music, there is really no reason to not track your runs using the built-in GPS. The apps provide useful statistics during and after your run. Likewise, It’s helpful to know your current pace and distance. It helps keep you on track and on pace with your desired speed.
