I have had the Sense 2 out for several run workouts. Unfortunately the current pace feature seems tremendously inaccurate. When I check I am running a 5 min. mile and the next I am running a 10 min. mile. It seems to jump all over the place. My route is almost always the same and the distance has been off. This has not been an issue with my previous Fitbits.
Best AnswerIn general, I don't have much problem with the GPS and distance although my Sense 2 tends to underestimate the distance. I never look at a pace so can't tell whether it's correct (I run by power, not pace). There is more problem with how Fitbit presents the data. Here's example:
There are two different paces and distances don't match between the app and the dashboard. The GPS distance (by measuring the GPS track) is closest to reality). If you need correct data when you run Fitbit is the wrong choice.
