As some of you may recall, I was not able to calibrate the stride length of my original Watch Sport. I tried to calibrate my Watch more than ten times over the last 11 months using each new version of WOS2. I always followed the instructions on the Apple Web site as listed below.

I reset the calibration data after installing the new WOS2 and then, did two calibrations runs of 60 minutes and 7 miles with my phone. However, as soon as I ran without my phone, my Watch would revert back to an "average stride" length that was much longer than mine. (i.e. I have a "shorter stride" than the average Apple was using) My Watch would record 9+ miles for every 7 mile run, so it was off by more than just a little. The total distance recorded each time was different for the same course and it seemed to be temperature related. It was so far off and inconsistent, that I could not use my Watch for anything more than a step counter and time tracker. (i.e. I ran for 60 minutes with 11,000+ steps, ran for 70 minutes, etc.)
With all of that said, I am happy to report my AW Sport SO with WOS3 is finally calibrated! I used the same technique listed above to calibrate my Watch two weeks ago and after six runs without my phone, I can say it is definitely working for my shorter stride length!
For my usual 7 mile runs, the Watch has been within 1/100 for each mile. On several days, it recorded the exact mileage as my Garmin Forerunner. On other days, it was off by less than 1/10 of a mile for my total run, which is well within the acceptable range of a GPS Watch.
I am debating on whether to buy the S2 Nike+ version once the hype wears off, but with the latest calibration results the urgency to have an on-board GPS has somewhat diminished. I am not getting the nice GPS maps I saw with my two calibration runs, but the distance is right on.
