trainingpeaks.com

Trainingpeaks.com was recommended by Garmin in their packaging. I think you can get a free week of 'Premium' by signing up with trainingpeaks.com/garmin. There is an agent you can load on your machine that you can upload the data with a push of a button and login with a push of a button... I don't find this site very useful for myself. No maps on it. Doesn't seem that user friendly.
