Issues with pace being way off

I am wondering if anyone else has any issues since last software update. I am pretty self aware of running pace, its been largely unchanged for years give or take a few seconds. I normally run a comfortable 9 minute pace, 8 minute when pushing it. Issue 1 the past 2 or 3 days my first mile pace is on average almost 11 minutes???? then my pace boomerangs to 8:30 or so. I am running same cadence same effort. This is relatively new phenomenon. I also notice that gps lock takes around 15-30 seconds when before it was almost instantaneous. Today wile running my watch randomly rebooted also. I also noticed that after the software install most runs I get a new record for fastest 5k or mile?? any advice? Do I nee dto maybe reset GPS?? if so what are ideal settings. Thanks in advance

This isn't a new thing. I observed that behavior of the first mile pace being much slower for months, but it happens only when GPS reception is poor, for example when I start a run on a trail with a dense…

Getting something similar it tells me I'm running 14 minute miles until it settles down. Was previously accurate from the start.

This is also happening to my runs since the update to 15.20 and GPS chipset 5.00. Frustrating for sure as it's become untrustworthy

This isn't a new thing. I observed that behavior of the first mile pace being much slower for months, but it happens only when GPS reception is poor, for example when I start a run on a trail with a dense tree canopy. And yes, the pace is often several minutes per mile slower, but then it mostly normalizes.

What's different now in your case is that perhaps your watch struggles to get a good lock on satellites which results in a poor quality of GPS data which triggers the pace issue. Perhaps you watch failed to update the satellite ephemeral data (which should be synced from Garmin Connect).

Well, all I can say is it started with 15.20 as others have said - so it's new for those of us that are experiencing it now.

Perhaps I'm being daft but I can see no option in Connect to update the satellite data.

So you simply sync the watch as normal? Did that before my run (as well as a after every run) and that made no difference whatsoever.

If you see "cpe current" in your system settings on the watch itself, the data is up-to-date. To update the data, you have to keep the GCM connected to the watch for a few minutes. I do this for about 10 minutes.

Never had to do that before, the only time I've ever had a GPS problem was when everyone did at the New Year. 15.20 has either amplified an existing bug as you claim or created a new one.

CPE says it's current but I'll check it before my next run. Thanks

My CPE is current, other devices in my household have not experienced this (Venu, Forerunner 45). I did have the issue all had back in Jan regarding GPS. And this def popped up with 15.20 for me, as tracks from last week before I upgraded are on point. But every run since has been shaky. Might try to switch back to the trusty Forerunner 935 and see how it tracks.

Or perhaps install beta software on the Fenix 6.

Yep, I have noticed this also. Usually do 10:30 mile or around that and now it reports a few minutes higher. HR is bunk too, I have noticed.
