I just bought the Garmin Edge 820. My other rides have all recorded total ascent for the ride. Today, my total ascent read 0. It should have read >800 ft. I uploaded to Strava and had it corrected. Why does the altimeter seem to work intermittently? I powered off and back on to record the second half of the ride and it still read 0. What gives?
I haven't seen any posts about Total Ascent not working. You could have a bad pressure sensor. What does the elevation profile look like when the ride is uploaded? Does it look okay or is it just a flat line?
The first half of my ride it looks like it started to record for a few feet, then flat-lined. After powering off and starting a new ride for the return trip, it's looks even weirder, but basically a flat line. I'm attaching a photo.
That was it! Something must have blocked the hole. I didn't realize that's where the altimeter sensor was located. Good info to have! Today's ride through mud and dirt and lots of hills recorded perfectly. Thanks!!
