Apple Watch Series 2 Run Distances VERY Inacurate!!!

All pace readings are way off. My trusty GPS running Watch has me at 4:45 to 5:05 mins per KM.

Apple Watch 2 thinks I was running at between 5:20 and 5:59 mins per KM. the first KM was 5:30 so no different to the rest of the run really.

Hi,

I've tried all of the above...numerous times...and none of it fixes the issue.

This has been going on for 4 months on two different Apple Watch Series 2 as Apple replaced the first one thinking the GPS may have been faulty...however this 2nd watch is just as bad.

The ONLY thing that seems to work is a full and total wipe and reset on BOTH the iPhone and the Watch.

This as mentioned takes me the best part of a day to do as ive so much data on my 256Gb iPhone.

Also for a whole days effort in un-pairing the watch, resetting the watch, resetting the phone, setting the phone back up again (as a new phone not a restore), downloading all my music and icloud photos etc, pairing my watch again as a new watch not a restore...it still only gives an accurate reading for the first couple of runs and then goes all out of sync again!!!

The first 1-2 runs are spot on, I can plot a 10km run on Map My Run and when I go run it with my Apple Watch I get all the way round and it will show a 10km run......but from the 3rd or 4th run onwards the distances are all over the place!

I run 5-6 days a week so its only correct for a couple of days before it all goes belly up!

I spent days, weeks, months trying to get an answer and nothing worked so I gave up and crossed my fingers that a software update would come out for the Watch OS which would fix it but nothing has come out as yet.

I still don't understand why the maps are correct but the distance can be so far out...the GPS has clearly tracked the entire run correctly so if the map/route data is all accurate how can the same route be showing as 4km one day and 6km the next!?!?! The watch is clearly using the motion/pedometer to track distance and only using GPS to plot the map.

It cannot be using GPS to calculate the distance or it would be accurate each time as the map it shows at the end of the run shows exactly where I have been so it has clearly tracked the entire run with the GPS.

I'm pretty much resigned to the fact that I bought a £600 GPS enabled watch for running...that's just never going to work!!

I just went and ran my 10km training route and took 3 devices with me, I had my Nike TomTomGPS Watch, my Apple Watch Series 2 and my iPhone 7 Plus (a big beast to take running!!) I switched off Bluetooth and wifi on my iPhone so that the iPhone and the Apple Watch were not connected and I could therefore track the run indipendently on both devices.

The results speak for themselves:

Distance tracked:

Nike TomTomGPS watch = 10.01km

Apple iPhone 7 Plus = 10.16km

Apple Watch Series 2 = 9.19km

Note: I started the iPhone a good minute and s half before the two watched as I started it at my front door and then messed about putting it in a running pouch and getting it zipped in and comfy...I then walked down my drive until the Nike TomTomGPS Watch picked up the GPS signal, at which point I started the two watches. This might explain why the iPhone has a slightly longer distance due to me starting it earlier and at my door, not up the end of the drive.

To have the Apple Watch nearly a kilometre out is just plain crazy...especially given YET AGAIN that the GPS route it's showing is correct. The Apple Watch clearly does not use GPS for distance/pace/average pace etc...it uses the HIGHLY INACURATE pedometer instead. THIS IS CRAP FOR ANY SEMI SERIOUS RUNNER.

If you look at photo of all 3 you'll see the route displayed on the watch is IDENTICLE to that on the iPhone. I've measured this route on MapMyRun and Google maps etc...it's bang on 10km, i have probably run this route 100 times in the last few years.

This just proves again how utterly crap the Apple Watch is for fitness and runners.

Sigh.

Do you not think I've done that already "deggie"??!!

Apple useless on this issue. Been months and no fix.

Had Apple Watch replaced with brand new one...same crap distances.

I've run plenty of officially measured 10k, 1/2 marathon and marathons.

Watch is ALWAYS way out.

PS as to why I'm posting on here!???...I didn't realise this was your personal forum?? I thought was an open space for everyone to get help and advice from fellow Apple users???

Hi Iudgats.

Yep, this was Apples final resolution. And it DID work...for all of a week. Then was back to its old VERY inaccurate self.

I've now done this TWICE.

Full reset and flatten of both the iPhone and he Watch then start from scratch and set up as new devices, no restore at all...all as new devices.

Watch then works a treat for about 3-4 runs...then bang - ITS TERRIBLE ALL OVER AGAIN.

Has yours worked fine ever since? How long has it been working for after the re programming as new devices as mine never lasts more than a week before it just reverts back to the inaccurate settings.

This is driving me insane...I just want my £600 GPS enabled Watch to accurately tell me how far I have run!!! Is that too much to ask...

Same run on same day with iPhone 7 and Apple Watch Series 2 at same time...distances 1km apart!!!

Maps...THE SAME!!????!!

Nike TomTomGPS Watch 10.01km

iPhone 7 Plus 10.16km

Apple Watch Series 2 states it was only 9.19km

I give up!!!

These watches are dreadful!!!!!
