Hi all
I have stumbled upon a site called Strava which enables you to compare Garmin data with other Garmin users. I uploaded a couple of rides on there the other day and already I have been compared with a few SPR folk. There are KOM sections (very handy for Sunday rides) where there is a leaderboard, it even gives you power out put estimates for your climbs.
It is pretty cool, I will do some more digging in there to see what can be done (There are a few other SPR folk on there already and SPR has been set up as a club).
The website address is: http://www.strava.com/
Go have a play
