Wayne made a comment on my post yesterday about the elevation data in BIM. I commented back that I thought it was just part of the file exported from Garmin or Sport Tracks. Since I was wrong, I figured it would be worthwhile clarifying.
First, when I exported the data from Garmin I did so as a TCX file not a GPX file as I thought which is what I export data from Sport Tracks to. BIM will import either data file. You can also export from Garmin or Sport Tracks to Google Earth for what it's worth. I haven't tried that but it might be interesting. Now as to the file on BIM I had forgotten that you get this message when you look at your activity
So I assume that is where they get their elevation data and you can see the file imported from Garmin is the same as I the one from posted yesterday except the mileage was different. Sport Tracks had it at 5.89 miles and Garmin had it at 5.88.
