The wife gave me a Garmin Forerunner 301 for Christmas and I've been playing with it a bit. I discovered MotionBased which is a really sweet online application for analyzing, sharing, mapping, etc. your GPS data files.
Before I join up to MB, I would like to try out as many of the competing sites as possible. I remember an article in Bicycling a few months back listing several that offer similar services but alas, I have tossed the issue out.
Can anyone recommend additional web-based applications or software for analyzing your GPS data files?
