As long as the weather is still not very good, I run in indoor track. Noticed the strange behavior of the watch. After a interval I change to a very slow step for a few meters, then another ~50 meters I walk at a slow pace, then I start jogging for 200-300 meters to the next interval. And most often (but not always) after the interval the watch starts to show 0 pace, which is annoying because it spoils the overall distance. Is it normal? Or is there a problem with my watch?
Example in the picture below (run\walk ratio shows that I'm moving).
