24 Hours of Booty isn't a race, so teams/individuals are free to ride as little or as much as they like. My friend and teammate, Stoney, doesn't ride anywhere near as much as I do; his goal for the 24-hour period is 122 miles, with minimal night riding.
(He is a hard-core, old-bike, Campy fanatic, though; GB, if you do stop by, you and he can totally geek out. He's bringing -- and riding -- all three of his vintage bikes, which he restored/built up himself: a Team Bottecchia, a Claude Butler, and a 3-speed Raleigh nicknamed "Christine," festooned with mirrors and bullet-shaped lights that would look at home on a '57 Chevy, and weighing in at, like, 500 pounds.

We both want to be able to enjoy some of the festivities associated with the ride, so I'll be playing it by ear. I don't have a specific mileage goal.
