Potresti trovare esercitarsi con Apple Watch: l'hardware perspicace. Adam è un corridore serio e anche lui ha notato la differenza nelle distanze misurate:
Accelerometer -- Happily, the Apple Watch does have an accelerometer that enables it to detect your steps, from which it can determine both distance and pace, even if you’re not carrying your iPhone. It calibrates itself when you use it with the iPhone around, and I’m impressed at how accurate it can be. After a few runs, its numbers match quite closely with those collected by my Garmin and with the quarter-mile markings on San Francisco’s Bay Shore Trail, where I was running recently. Unfortunately, accuracy drops significantly if you run uphill (where your stride is shorter) or faster than normal (where it will be longer).
