Fenix 6X Pro - whats wrong with pace and gps track?

I am having same problem pace is not working right

Why doesn't Garmin make a statement about this? I have the same problem, and this is 7 months after this topic was written.

Same issue here as well. I just upgraded from a Fitbit Ionic to the Fenix 6 Pro primarily for the battery life and added map / course routing functionality. I thought at a minimum the pace, GPS, and related function's would be on par if not better however I find that the pace takes a good 10-15 seconds to catch up where as the Fitbit seemed to adjust instantly.

Just to follow up, I sent this watch back... Ran with a FR 945 in parallel 10 more runs, and the Fenix 6 pro was always 3-6% off the distance / pace of the Forerunner 945.

After the switch from Suunto 9 to F6X I suffer an issue with useless momentary peace. The track quality is also less accurate. I observe this on each version of firmware released for two months I've got the watch.

I am one more person with the same terrible annoying problem and i have this watch 3 months now. The gps is not so terrible(maybe not the most accurate), av.pace is somehow correct -  i believe - but the pace is insanely inaccurate. I can't understand how the av.pace is accurate and the pace is extremely inaccurate, it doens't make any sense. For example i run 1km and the watch shows me 5.30 av.pace which i believe it is correct, but during this km the pace indication was from 6.50 to 7.00+(most of the time) even 8.00 some times. From the other hand with cycling i don't have any problem or inaccurate measurements. The most annoying thing is that Garmin doesn't give a s... so far, some kind of announcement - a responible answer. What a shame....

Same here! I have Fenix 6X for a month and set up Garmin coach 5k training. One workout was run in pace 7:55-8:33, but when I started to run at desired pace, F6X shows pace 2-3min/km more than I run. While I ran all workout in same cadence, I see several drops in pace. It is useless to have such watches, which tells you to keep some pace, but they can't measure it live. Average pace was better - in tolerance. And even more, no training status was calculated due to pace drops. 

From TOP model of sport watches with premium price, I expect 100% working base functionality, like pace, GPS tracking,... I don't need to buy $850 watches which gives wrong data, for that is better refund Garmin and use phone with Strava tracking which works 100%.  And what piss me off  most, is Garmin ignorance. Time for users to say goodbye to Garmin, maybe then will act and fix bugs. I recommend all friends and community to read this before buying Garmin watches, then chose to better quality watches from competitor.

Exact same problem. It was so freaking frustrating spending 700 on a piece of hardware that does not work at doing the simplest math averaging on a rolling window of samples. 
it is so frustrating I spent 10 hours minimum doing video demos demonstrating the problem to Garmin Iberia support. I called, I mailed, I went to the shop. This is a freaking SCAM. A 130€ suunto or a 60€ android smartphone does a better job. 

I tested under so many circumstances and it is so freaking random.

Today I ran a wide and straight city avenue at 4:30 min/km. The watch showed a pace between 5:50 and 7:30 all the way. Until LAP was triggered and then I could see the pace was actually 4:30 (on lap). 

Shame on you Garmin. This is not a product you can sell.
