Mapping sites and ride data
I posted the msg below over at the Garmin forums, but figured I'd get a wider response here at bikeforums.net
I have an Edge 305 (2 years old).
I upload my data to GTC, Garmin Connect, and SportTracks.
I have always had issues determining (with any degree of accuracy) what sort of climbing data I experience and is being reported.
Here's an example of a ride I did yesterday: 63 miles.
GTC reports 2789 total ascent.
Garmin Connect reports 3234 elevation gain
Bikeroutetoaster reports 1430 ft ascent
RidewithGPS reports 2638 ft elevation.
Of course, SportTracks reports different values depending on the amount of data smoothing applied, so I left that out.
I'm not sure why I keep bashing my head against the wall on the elevation issue, except that maybe I hope that by doing the same thing over and over, I'll get a different result one day.
Have you guys found any particular mapping program to report reliable elevation for the route? My numbers above are ridiculous.
I mapped the same ride on the following sites:
MayMyRide: 1132 ascent
Veloroutes: no elevation data that I could find
bikely: no elevation data
GPSies: 1988 ft
bikemap.net: no elevation
Training Peaks: 4593 elevation gain
More data... just all over the place.
