Race S wild pace/ elevation inaccuracies

[jstew5]

Hello,
I am experiencing serious elevation gain/pace issues with my watch, and wanted to see if anyone else has experienced this.

Yesterday on a climb of around 1500-2000 ft, my watch was recording consecutive 3 to 4 minute miles, each with an elevation gain or loss of 2000 ft per mile. by the time I had reached the top of my climb, it said I had traveled roughly 15 miles, and climbed over 30,000 feet, it said my fastest pace was 1 minute per mile! It was more like 5 miles total distance with about 2k ft vert. I was using navigation if that makes a difference.

In other runs I’ve experienced this issue, but never to this extreme.

Has anyone else experienced this and came up with a solution? I want to like this watch but it is making it very hard to do so.
