RunningAhead.com

A little clunky, but not a bad little site. Easy to transfer data to it from your GPS. Still playing with it. I like that you can simply send your 'profile' link to somebody... You don't need to send each individual run.

Maps (Courses) can be created, but you can only save in *.GPX format. Most likely you would need to import into mapmyrun and then export into *.tcs format for the Garmin product, but I havne't played with that yet.
