Standing to pedal, is my guess. Which is interesting because the most famous English bike racing commentator often describes a graceful climber as "dancing on the pedals." But I'm guessing that this particular motorist probably doesn't watch a lot of bike racing on t.v.

As for my commute today, it was just wonderful. It's still unseasonably cool here--we're usually over 100F/38C by the first of June--and breezy. But at least I get to wear my favorite long sleeved jersey. I recently increased the gearing on the FG because I felt like I was spinning out on the open road. Only 6 gear inches more (42x16=69 to 43x15=75) but it was suprisingly heavy in the headwind. But once I crossed the Sacramento and turned back north, it was smooth and fast.

I had a nice chat with a guy in the full racing team kit for a while. Then he said "I'll let you get back to your ride" and pulled away with ease. Bastard.

And then back into town where there was actually a back up of cyclists on the Tower Bridge. Good to see that.
