Overestimate distance ofr outside activitieso

For the last couple months, my watch is reporting distances that are at a minimum 10% higher than the tru known distance. For example for an eight-mile route, it records live that I have gone ten miles. It used to be much more accurate.

when I look at the map. I notice that there are now multiple times that the line for my course juts off-course for at least a quarter-mile, and then it comes back. I believe that these mapping errors are the source of the overestimate.

what setting should I adjust? Thanks!

Ultratrack is, as you say, low accuracy, for very long distances. Tree cover can also cause inaccuracy, as can being in deep canyons (urban or rural). Multiband can help with some of that.

Whereabouts in the world are you? There are several areas with conflicts nearby where active GPS jamming is in use.

Do you have the watch set for "Satellites: All + Multi-Band"?

Another problem can be where tall buildings reduce the area of the sky that is visible to a thin slit.

Thanks for the response!

I checked the satellite settings. No they were not set to multi band. They were set to ultra track which says it’s good for the battery, and bad for accuracy. I’ve changed that, and I will give that a try!

I am in Seattle, WA, and the majority of my activities are in the Cascade mountains.
