I have been searching how to fix this error for quite some time, and I can't find anything regarding this error.
Anyways, I recently just started biking, since the weather got warmer. I always click the cycling button before I start biking. The last few times of recording them it has been skipping areas I cycled on (roads). I noticed, when I look at my watch it resets the whole workout (timer, distance, miles, etc). So that 1 hour of workout became five workouts and not one workout. I do have my phone with me as well as I have my watch keeping track of GPS. I can clearly see it's skipping areas. It draws a map of the trip.
Here are some workouts of pictures, I have done. You can notice that there is five workouts. But the first one I clicked workout on as well as the last one. The last one I realized that it's wasn't recording. Also, you can tell that it messed up on the 3rd workout day.
