Gps running pace is incorrect outdoor

I’m a average runner. I usually run 6:00-6:30 min/km. But when I do a run, the last several weeks my watch tells me I’m running 1:30-1:35 min/km. And I’m sure I’m not that fast. I tried to change the satellite to automatically selection. But no beter results then all-+multiband. I have the latest software. I have no clue how to get my watch working normal. It’s frustrating, my watch was working fine for 2 years. I live in an open environment. Nature, grassland and open forest.

Have you tried any of these:

1. Done a soft restart - hold in light until watch shuts down completely , then restart

2. Software reinstall - Settings > Device then press light 8 times then select reinstall software

3. Sync'd with Garmin Express on PC / Laptop

Does the distance and track of the runs look correct?

Are you using an external HRM like HRM-PRO at all?

i have done option 1 and 3 several times. now I tried option 2. Let's see what will happen. The distance and track of the runs look correct. And I don't use external HRM. give you an update tomorrow

If so, how long does it take you to run that distance, is your average pace normal? And how does it compare to the pace chart for that distance?

I don’t understand, pace average is 6:08. But it shows 1:40 on the watch during the run and on Garmin connect

I had problems with the jammer, but they are immediately visible - you are standing still and the coordinates are running and the watch shows the speed of tens of km/h. You look at the map on your phone (standing still) and it shows that you are rushing in the middle of the river, well, and the route on the Garmin looks wild. But you have something else.
