Hello, I have a recent problem regarding the running paced showed by my Forerunner 945. First time was 3 days ago, I was almost sprinting and my watched showed a pace of 5:30, which is far lower than my usual 4:00 VMA pace. I figured it was because I was trailing in the forest and maybe my form was bad. However, I attempted another VMA exercise today, on a descending asphalt road and my watch showed a pace of 5:10, which I know is wrong. My watch showed a track of 1.48km while google maps showed 1.65km. My watch showed as well a total elevation gain of 120m while in reality it was barely 30m (this is clearly showed by the altitude graph). I run with a Garmin belt HR pro plus as well. Do you know what could be the issue?
Thanks,
Best regards,
Christophe
