Our story is here:
http://www.dishers.com/2010/06/01/my-2010-mason-dixon-rallyNot too shabby for (3) guys who rode together all-the-way.
Two riders are not as fast as one and three are not as fast as two. That being said, I don't think the hit we took for doing so was _that_ bad. We've all ridden together for probably 20,000 miles, maybe more.
We ran a good route, not too conservative, but certainly not over the top. We did however get 4 hours of sleep (min requirement was 2.5). So that extra 1.5 hours plus the time dicking around (probably 5 hours total) was 2.5 hours less riding time than the top guys. That's probably 200 more rally miles.
Bottom line though, we finished, finished respectfully, and didn't feel beat to shit the following day.
Good times.
