Today I rode 41 miles. There was a bit more wind than last Sunday, and my average pace was slower. I did, however, make several efforts to get up to 20 mph -- and succeeded! I can't sustain such a speed for more than about five seconds, but for me to hit 20 mph at all means progress. Gee, maybe I can start dreaming of a sub-5-hour century??
In fact, that's long been one of my impossible cycling dreams. About a year ago I added another: successfully completing Paris-Brest-Paris. I suspect that I'm more likely to be able to do a double century than either of those!
