I just completed the bike course of a new 70.3 and am trying to figure out the elevation profile of the course. I used my Garmin 920xt which has the elevation function, but it hasn't been functioning for over a year. I can down the the GPX, etc. files and upload them to Strava, RideWithGPS, etc. but I am trying to figure out how to use that file to determine what that exact profile and share it with people who will race it in the future.

I hope that works and I look forward to your guidance.
