Strange cadence problem (Hunting cadence)

Former Member over 7 years ago

I have been using forerunner 935 around 4 month. I found some problems.
1. Every time I do the running, but when i check the cadence, some times appered to be 90, and then change to 160. After that, change to 90 again. again and again.( Normally, my cadence is around 160, and speed is 6.5min/km.)
2. Some times, the appered cadence data remained unchanged.
3. I have upgraded the soft ware for some times until 5.40, but there is not any change.
4. I compared this data with some other running APPs, the result is same.

Does anybody have the some experience?

Hi I've experienced this as well with my 245 and 945 after a few months using them. Any solution aside of reset them?

So far, I did not get any solution. I ever tried to reset to factory setting someone mentioned, but it did not help.

Exact same issue here. Are you still experiencing this issue, 4 years on?

My cadence switches between 180 and 90 during the run, skewing the average cadence values to 110–130 SPM typically.

I've been in contact with Garmin Support, had several back-and-forth emails, but the only suggestion has been to restart the Garmin. Since then, radio silence. It's quite annoying, as I did used to use the cadence reading to keep my form in check. Historically, it worked fine, then suddenly this issue arose.

Have u tried with external sensor i.e. other watch or pod to compare the data? Have u tried lending your watch to your friend who has similar cadence with u? I tried both and found out the watch was alright all this while. I then record my video of running and noticed my arm swing is not obvious moving forward and backward hence the accelerometer in the watch couldn't capture the data. Another thing to try is, go with strength mode, try to do push up. If the watch can detect your rep correctly then your watch accelerometer is working well. Check your arm swing. I have solved mine.
