I'll just add that Ken is a great guy ... very friendly, and not at all condescending to those of us who are not as fast or fit as he is. He and I have met and talked on a number of 1200K randonnees and a fleche. We also exchange emails now and then, and I'm toying with the idea of doing a series of brevets he is putting on this spring.
As Rowan says, he also has a lovely wife who supports him on his rides, and he travels a lot.
bmike, yes I believe he has done exactly what you mentioned. Rowan and I were talking to him about that before the Last Chance Randonnee in Sept 2005.
