my samsung watch along with what it syncs is saying i ran 2.8 miles. However on samsung health there is also a tab to start a workout that tracks your gps running which i did today. It says I only ran 1.75 miles. How on God's green earth could be be off by that much?
Do i have to calibrate my watch or something? I typed in my profile correctly with height and weight. How else can you calibrate it?
