On my first century I had the honor of riding next to a gentleman on a 1996-ish Paramount Full Suspension mountain bike with semi-slicks. I thought wow I'm gonna have to wait for this guy. Then he tells me along the ride he didn't take his road bike because he had done 178mi 2 days before the century and broken something on the way home. @#%#$! 178 miles!!! And this guy had to be about 60-65. Anyways towards the end we came up on a local team and he proceeded to draft off the back on his F/S Paramount at about 24-28mph while I was dying on my 3x9 Univega roadbike. After we got back I collapsed on the lawn of the starting point while he brought me a punch and proceeeded to tell me I "rode great". Man NEVER underestimate the old guy on the funky mountain bike on a century ride.
