Apple Watch Calibration issue
Hi...so I've had the Watch since it came out. for the first month or so, the distance was fairly consistent to the treadmill i was using as well as the Nike app. However, for the past couple of months, the distance indicated in the Activity app is usually about 20% more than what i'm actually running. I just did a weekend with a 5K, a 10K, and a half marathon, and all three registered similar incorrect distances. My iPhone was with me stationary on the treadmill, but was on an armband during this past weekend's runs. Anything to help me get this working better would be appreciated...its VERY off. thanks
