Apple Watch 4 / Watch OS 5.2 / Paired to an iPhone XS iOS 12.2 Anyway every morning i get up and do a cycle. Boring ol' me same route every day more or less the same pace. I have a bike computer which is calibrated by the wheel diameter. I basically do the same 10.40 miles every morning. I throw on my airpods, some Spotify, reset my bike computer, start a cycle workout and go at it. Except, my workout is cheating me and sometimes its a lot. Like today, the speed and distance wasn't showing and at the end of my 10.40 mile cycle, it showed only 7.48miles, which of course reduces the speed by a substantial amount. Pretty much making the workout app useless to me. Weird thing is i had an original launch day Apple Watch, which started selling me short, but i though ok it doesn't have its own GPS, so i'll let it off, but then when i got my new Apple Watch 4 when they came out, it was working great. Giving me more or less the same as my bike computer. I thought it had finally was not cheating me anymore. But it just seems to be getting worse and worse now. I really shouldn't care. I'm not exactly getting any faster with age. Its just that where i work, actually collects our data and gives us financial incentives like gift cards and so on, for being active. So its probably costing me $100 here and there. I've hard reset the watch, always closed down any background apps on the phone and watch, restarted the iPhone even though that shouldn't have anything to do with it given the watch has its own gps.. But its just so hit and miss, more miss recently. I can't imagine it being a hardware issue. But then again, anything is possible. Am i the only one who has this issue. I know some runners and cyclists take their exercise a lot more seriously than i do, and this must annoy the heck out of them... Unless i am an isolated case ? Any advice ?
