ORN: 30 min X 2, city bike
I had a meeting downtown, so it's a good excuse to get up early and ride in. Riding the city streets has it's own rewards and hazards. Dodging taxis, buses, pedestrians, and tourist makes for an interesting - and challenging - ride.
It's almost like interval training. I try to pedal pretty hard in between stops and maintain a speed close to the traffic. It's a good workout.
