I'm slowly dragging myself into Training, as opposed to just going out riding. Bought Bike Racing 101, and one of the workouts in it is called the Push Ride: ride at recovery up to endurance effort at 70-80 rpm. The book mentions this is a tiring ride. Ok, cool. I did that ride yesterday, and yeah, riding around in the Big Gear was tiring, but I'm not exactly sore today. Should I be?
