    Total Ascent - Edge vs Training Center

    Does anyone know why, for any particular ride, the Edge reports one set of values for total ascent/descent, but when the data is uploaded to Training Center, different values are reported? I've found that the values in TC can be 10% or more different from what the Edge reported. I've seen this with both the 305 and the 705.

    This is discussed at length in other posts. Simply, the software is not using the recorded elevation from the GPS. The software overlays the track on a Digital Elevation Model (DEM) that is simply a raster image where each cell value is an elevation. Cell/pixel sizes are usually 30mx30m. That's all.
