OK, hang with me on this one as I attempt to build an argument.
I just got back from a tough ride. Just above freezing with wind gusting up to 25 mph. Four layers of clothing and still feeling cold riding into the wind. As I was headed into the home stretch, I thought the ride felt four to five miles longer than it was. This triggered the following:

1. If pros in the major tours earn extra time for top place finishes or other "incentives" during a given stage, why shouldn't I earn extra miles for especially difficult rides?

2. Everyone knows that circulation begins to slow once past 50 and this results in a whole host of disadvantages when it comes to performance in cold weather. Not the least of which is a serious reduction in motivation.

3. So, 50+ riders should be able to add one extra mile for each 20 miles ridden when the temp and/or wind chill factor go 10 degrees below freezing. (This is only a suggested formula. It is open to debate and review by other 50+ members.)

4. Disqualification would occur should the rider take in any performance enhancing substance during the ride. Hence, a stop for coffee and blueberry pie would wipe out any extra miles that might have been earned. (Or tea and biscuits.)
