Subject: RE: route elevationYeah, it was off for me too. The first time it was a 49.9% grade hill for over 3k' on a 3 mile run, logged off and logged back on, it was the same elevation change but only 19% grade, reset it as suggested and it calls it 361' total gain. The entire time, the elevation profile was correct. I was wondering how average grade was calculated, since none of my out and back runs have a 0% average grade either here or on google earth. Mapmyrun doesn't output average grade just the grades of significant hill climbs. For the route (posted below) I purposefully just took the (mostly) downhill portion of my run and mapped it expecting to see a negative average grade and gain. Are the triangles on the elevation profile used to calculate slope, since they seem to have a net elevation change value (with respect to the start)? How are the triangles placed? By slope inflection? Any thoughts? http://www.beginnertriathlete.com/discussion/training/map.asp?routeid=162882 Edited by raeray80 2011-07-22 11:04 PM
