Apple Watch - Running inaccurate

I run with my apple watch daily. Recently, my pace has been a little slow, but it was believable. However, I did an organized 10k this weekend and my watch said I was 4 minutes slower than my final race results. Each mile split is about 30-40 seconds slower than the splits the race clocked. What's going on?

Run Pace Apple Watch Accuracy I have a series 6 Apple Watch. I've had a series 1 and 3, and have been using this series 6 for over a year. Randomly this past weekend the watch started logging my run pace much slower than ever before across any watch I've had. When I say slower I mean by as much as almost 2 min/mi average mile pace slower. For example. My general 5k pace is around 8:40/mi. It has logged me in the past just fine, and even when I've done 5k races has been very close to the same as the actual race bib I am wearing. Now I will go out for a run at what feels like that same speed and it says my pace is over 10min/mi. I have powered down and back on. I have done all the recalibration tricks. I tried wearing it one notch tighter. Nothing has helped. The pace for my runs this whole week show me going significantly slower than I ever have in the past. Could a sensor be bad? Maybe a bug with the latest update? Random GPS issues? I'm not running anywhere remote or different however. I've done all out sprinting and it shows me not going much faster really than what I would do on a normal average run. Help!

Apple Watch Ultra very inaccurate in running I upgraded from v7 Apple Watch only to find that the accuracy of pace and distance on my Ultra is extremely poor. To put this in context I jog with a group of 5 friends twice a week and when we finish, my pace and distance are WILDLY out. For instance last night my distance was 5.36Km and the others using Garmin, Fitbit etc were all on about 6.2km or thereabouts. Obviously my pace was wrong too and this occurs every time. I'm very familiar with Apple Watch having had the 7 for a year and I have followed all setup recommendations to the letter, location services, reset fitness calibration etc. etc. It seems to me that this watch is a dud and needs replacing

Apple Watch Indoor Run Accuracy Hi, I’ve seen this question asked a lot but no one has been able to give a good answer so I’m hoping maybe there’s something new out there. I have been running on a treadmill and specifically got my Apple Watch to track my runs. I have run outside and had no issues with the distance accuracy, but on a treadmill it’s another story. At first it was accurate maybe off by about 0.02 or something that didn’t matter. Now, about 3 years later and it’s off by more than a quarter mile and sometime even 0.5. I’m running 2 miles and It’s telling me I’ve only gone 1.5miles or less. This is really frustrating because all my workout data is inaccurate and it looks like i’m running 1.5 way slower than I actually am. I’ve seen people say to reset the calibration but I’m curious what this actually does? When I click reset there’s a disclaimer that pops up telling me that if I do it, my workouts will be less accurate, seems counterintuitive to me. Not sure why Apple is putting that disclaimer there if it’s supposed to fix the issue. Anyone have a fix to this? Apple Watch Series 6 Version 9.3.1 (20S664)

Either you'e running slower, or the Apple Watch is not correctly calibrated.

Try and calibrate it again and see if the issues persist
