I recently acquired a sports GPS watch and I tested it out for the first time today.
Here's my route exported to Google Maps.
And even better, to Google Earth.
And some key statistics produced by the unit:
Vertical ft: 12,762
Maximum speed: 40.8 mph (much faster than I thought I was skiing)
Distance skied: 10.4 miles (much further than I would have guessed)
Time skiing: 49:21
Time stopped: 24:52 (it's Spring Break so there were some lift queues)
Time riding lifts: 1:04:11
