Lance has been using MotionX-GPS to record tracks skiing and mountain biking. Then he uses GPS Visualizer to see the elevation profile of his track. It is simple, just email your track from within MotionX-GPS with the one touch “Email Track Now” button and the KML file gets attached to the email. Then upload your file to GPS Visualizer to see the elevation profile.

Lance also said, “I also have an upcoming epic mountain bike race. I use profiles from my training rides to try and match the course profile for training purposes. I actually never thought I would consider mounting the iPhone to my handlebars until your software came out.”

Here is the elevation profile of his latest track while skiing.
