Love my Apple Watch but I am finding in standalone mode my pace and distance is way out. My last few runs I know I have run about 9m25 per mile but my Apple Watch records this as over 10 minute miles. My husband takes his iPhone 7 and records the run and i believe the pace on this is much more accurate. Is it worth recalibrating the watch and doing a few 20 minute sessions like the Apple site recommends? When I first had the watch the pace seemed to be fine but the last few runs it doesn't seem right. Could it be the latest update on it that messed up the calibrations?
