had a pretty special experience this morning. a friend of mine works at one of the companies sponsoring Stephen Phillips in his attempt to break the around-the-world cycling record: http://www.globecycleracer.com/index.html
Stephen arrived in Boston last night, and so my friend invited me to join him and some co-workers to ride a 10 mile stretch with Stephen from Burlington to Concord center. (Stephen then did another 90 miles after that - it's roughly a century a day I think.)
What surprised me most was how "regular" his bike is. Nothing fancy, pretty much an MTB with an IGH and a disc brake in back (v-brakes up front). not even a belt drive, just a regular chain. cool thing was that he uses the same rims I do on my commuter (Sun Rhyno Lite).
who knows if he'll break the record or even finish, but it was pretty cool to rub shoulders with a potential record holder.
(and since you are wondering, we only averaged 12.3 during those 10 miles. he didn't seem to be in a rush)
