Today I used my Garmin to track my commute AND my clipless pedals for the first time on my commute. SRS BSNS.

Anyway, still getting the hang of clipless. Clipping is tricky, but unclipping is really easy (maybe because my pedals are designed for newbs like myself). I didn't feel THAT much of a difference, though uphill was relatively easier than with platform pedals. Afternoon commute will tell more, when I don't have a headwind to fight.
