Perfect conditions have a dark side, too, though. They remove all excuses and show you your true level of preparedness. By contrast, if I were to go out and suffer through a rain-plagued, flat-tired-epidemic of a ride, and do poorly, I would extrapolate (and compensate) in my mind: Well, if conditions had been better—and surely the next time they will be—I would have been fine.
Saturday's ride showed me the best I could expect—from my body and from the Brevet Angels. And I judged that, given how I was feeling and performing on such a perfect day, it just wasn't good enough when one factored in: triple the distance (at PBP), the likelihood of some rain and flats, lack of sleep—PLUS hills, hills, and MORE hills.
So with the stats gained from Saturday's ride, I have decided to put PBP off for another 4 years. Watch this space.
