The eve of the 150

Tomorrow, I will be participating in my first MS150 ride. My friend Daryl, who is turning 40 this weekend, told me years ago that he wanted to do one of these events before he turned 40. Even though he now lives in Nebraska, he is driving down to participate in the event that is only a few hours from where I live in Arkansas. Obviously, I had to join him. Now I don't consider myself a roadie, but I did trade my 29er to my friend Wynn Peterson for his Specialized Roubaix when I got back from the Colorado trip, and that's what I've been riding to work. I confess it is going to be rough going back to the mountain bike as a commuter. I think it's only a matter of time before I have a road bike for commuting.
Am I ready for tomorrow's event? Hardly. I haven't done any extended rides to get ready. I have done a 75 mile ride in one day before when I lived in Amarillo. I participated in the Tour de Cure. However that ride was FLAT. This is the Ozarks!
