I like to use Climbing Analysis to track climbing for mountain bike rides. Sometimes I forget to turn my GPS off at the end of a ride, so it continues saving track points, overwriting early portions of my route. For out-and-back rides, I could simply re-use the same data for the lost portion if I could reverse the route for the Climbing Analysis. I know I can use the "v" key to do this with the Profile Tool, but how can I do this for Climbing Analysis?
