Intensity minutes not recording for cycling activities using a Forerunner 35

Intensity minutes won't count unless your heart rate exceeds certain level for a prolonged time. Maybe you're not pedaling hard enough?

... or perhaps not wearing the watch on your wrist, and rather on the handlebar instead?

The watch is on my wrist and I can see my heart rate on the watch.

My Avg. heart rate during my ride to work this morning was 149bpm over 37 minutes duration.

Is the HR properly recorded on the Health page for the time of the activity?

... also check the HR zones on the page of the concerned activity. It is the tab Time in Zones below the graphs, and there should be some time spent in the orange and/or red zone. ...edit: err, in fact the green zone (aerobic) should count too

Yes.

By the way... Thanks for responding and trying to help. Garmin support had nothing for me.

Yes, the HR is fine. Looks weird. I'd try couple of things:

1. Log out of the GC Web account, clear the cache of the browser and log in again
2. Enter the activity, edit some minor unimportant value, and save the change
3. Go to the Intensity Minutes page and force reloading

Not sure at all whether it helps, but it may be worth of trying

BTW, make sure that in the meantime you did not edit for example the date or time of the activity. Also have a look whether your watch shows the right time. Did not you for example change the time zone recently?
