I did a smidge over 20 miles this morning before church with no ill effects on the knee, but I did have a tough time stayin awake during service   :o. Biking......I can see getting passionate about it especially since I have such a superlative place to do it. I have decided my goal this winter is to go around the big "O" which would be right at 100 miles. It is all flat so I think I have a good shot if the wind doesn't kick up.

Just remember that your objective is more about muscle than mileage.  If you think you need more of a workout, lower your tire pressure and/or add a bit a drag to your rear brake.  Its amazing how much more energy it takes to peddle a "de-tuned" bicycle.
