Elevation Accuracy - Garmin vs. runningahead (Read 87 times)

    This might be a silly question, but...

     

    Which is more accurate at elevation, my Garmin 405, or mapping the route through runningahead? For example, I have a route that my Garmin says is +/- 289 feet, and runningahead says is +/- 506 feet.

     

    My gut tells me Garmin is more accurate...but I thought I'd see what you all have to say!

      RA (which uses Google Maps) is generally going to be much closer to reality. GPS-based altimeters are notoriously bad.

        Your Garmin is way off. Elevation is very inaccurate in GPS devices that do not have barometric elevation assist.

        I've done my best to live the right way; I get up every morning and go to work each day...

          The elevation profile from RA will be much more accurate. However, the +/- calculation seems to typically be high by 2x or so. Depending on terrain.

            Someone had a nice post showing their garmin recording the elevation going up and down, whilst it was laying stationary on their couch.

            It's a 5k. It hurt like hell...then I tried to pick it up. The end.

              While not as fancy as jog-mowing, my couch does has some serious hills. Here's a HR chart of me laying on the couch when my Garmin was still a shiny new toy.
