Forrunner 620 missing vertical oscillation and ground contact time

Former Member over 11 years ago

I ran with my 620 and HRM for the first time today. I noticed in running dynamics that metrics for cadence is there but I'm missing vertical oscillation and ground contact time. Any reason why?

Same thing happened to me today. It recorded it yesterday for my race, but not today on the recovery run. Cadence and heart rate are there but not ground contact and vertical oscillation.

Same here. Yesterday it worked/showed, today, nothing. Awesome.

Same problem for me today. I'm a bit annoyed since today was my 28k run. I would really liked to have seen the effect of a long run on vertical oscillation, but I can only see Cadence. Maybe this is due to some error when the sensor is connected? It worked fine on the 10k friday...

Same for me today. Worked well for more than 10 runs before.

Deleting the HR sensor and re-adding it seems to have solved this for me. The way the HRM is added at the factory must cause the pairing problem.
