If you use a site like ridewithgps, something you may want to know is how to calculate the average elevation for a trip. Unfortunately, most sites don’t seem to provide this, so we have to do a little hacking.
Here’s what worked for me:
- download the GPS TCX file
- grep out the altitude lines (
grep -i 'altitude' your_file.tcx)
- find & replace out the remaining XML tags and whitespace using a basic text editor
- average the remaining values in a spreadsheet
Takes about five minutes. For my trip the number came out to be 10,753 feet!
