This is probably a stupid question, but does it make sense that if you walk during a run without, the distance is way off? I did an Outdoor Run and ended up walking most of it because I didn't feel great. I had my phone in my pocket and the end result was 2.76 miles. I assumed this would be accurate, even though I walked, because I assumed it would use GPS. I did the exact same route next day, and ran the whole way. This time I didn't have my phone, but the Watch has been calibrated with the phone for several runs and walks. This time it reported 3.5 miles. I'm thinking maybe walking during a Run workout with phone in pocket has re-calibrated incorrectly?
