Nice accomplishment GFish!
Up to two years ago, I rode a century almost every Saturday. For me, it was just base miles training for the PBP. Those plans were altered by an inattentive driver.
Now that I am getting back into the groove again, I have no desire to do a century as a goal. I just ride until I don't feel like riding. 20k or 160k, makes no difference. Of course, if I decide to do the PBP again, I will ramp up the distances again.
