I just found this website today... you can upload your GPS tracks to it and it will visualize your flight using bing. Super easy. Here's a flight of mine from February as an example:

Also, they've added multitrack visualization as of November, if you upload a flight that takes place at the same time/location as other pilots, it will automatically give you the option to visualize all flights at the same time. Pretty sweet!
