I have been looking for a good way to share my GPS data from our last skiing trip. It turns out that Garmin has a website called motionbased.com that goes a good job. I had to gzip the Garmin Trainer export file before it would upload.
I tried a couple things with the GPS, on Saturday I would hit start at the top then stop at the bottom, on Sunday and Monday I would just hit lap at the top and the bottom. Hit lap means that you see the lifts as well as the skiing, interesting for checking with chairlifts are the fastest.
