Hello there,
I'm recovering from an ankle injury and interested in one metric that just disappears, 2 times in a row now.
Chest strap stops showing ground contact time balance after a long pause (20-30 mins).
Usually my training is as follows, a few km of warm-up (pause here), then special running exercises, general physical preparedness and then (unpause) interval work and cooldown. In the pictures you can see that it shows only the warm-up, the rest is empty.
I would assume that the sensor is off, but the respiratory rate (which is not included in the running dynamics from the watch) is still in place like all other metrics.
Also yesterday a strange thing happened with cadence, it hovered around 180, even on segments where I obviously did not run 180, only a small part in blue shows the increase in the first interval.
