How to fix fitness calibration data in Apple Watch?

how to fix my watch? I decided to try and recalibrate my watch data because my watch started to take off .25 miles off every mile I had been doing. But it didn't fix the distance and now my calories burned is signficantly less than normal. watch distance randomly started taking off distance during runs + walks

Discrepancy in how Apple Watch compares Walking Speed data with Walking Exercise data I work out by walking on a treadmill in the basement of my apartment building. Yesterday my Apple Watch Series 10 recorded that I'd walked 33 min and gone 2 miles. A little arithmetic shows that if you go 2 miles in 33 minutes you're walking over 3.6 MPH. But for Walking Speed my Apple watch says that my range yesterday was 1.8-2.8 MPH. This is a large discrepancy -- 2.8 is about 22% less than 3.6. I realize I can recalibrate my Apple Watch, but the recalibration appears to require walking *outdoors* for 20 minutes and using the Watch's GPS. (Note: the Watch has always had accurate details about my age, height and weight.) And in any case the recalibration seems unnecessary; if the Watch accurately recorded my treadmill session it knows I averaged 3.6 MPH during the workout, so it ought to use 3.6 MPH as the upper limit of my Walking Speed -- not 2.8 MPH. Is there any way to minimize the discrepancy between how the Watch displays Walking Speed data and Walking Exercise data? I love all the data my Apple Watch gives me, but this glitch baffles me.

Apple Watch calories not tracking accurately during exercise Recently got the new iphone15 pro and updated to latest phone and watch software. Suddenly, Apple Watch Ultra is no longer tracking calories accurately during a run, and seems to be treating it like a walk of the same duration. Heart rate seems accurate, all my health details are accurate, but instead of 400 calories burned, since last week it is now at circa 150 calories. Have unpaired and repaired, switched on and off. Not sure of any other fixes. The GPS is also slightly off and missing say 0.5k of a 5k run.

Apple Watch displaying miles instead of kilometers during workout I’ve changed the settings in my health app and workout setting from miles to km, but during the running workout the number on my watch is still in mi. Only when I’m finished the data shows in km. How should I change this? [Re-Titled by Moderator]

Do you have your iPhone with you when you start a workout?

Can you compare the distance on a map and see, if tracking signal somehow lost contact to GPS?
