The older I get (64) it seems a good warm up gets more difficult. Of course warm weather helps, but even then there is the problem of getting that "second wnd" which comes after the heart rate and breathing goes up for a while. A good riding friend told me if he is expecting a spirited ride, and he has time, he will pedal over to a moderate to tough hill, climb it, and pedal back. He said he is then ready for the ride even if it starts off fairly fast. Maybe that is what I need to do, but looking for oher tips.
