Luker, I like that conversion. I've considered multiplying my mtb hours times two as I can usually ride a road bike twice the length of time I can ride the MTB before tiring. Mountain biking is a young man's sport and, unfortunately, when I'm on the trail, I know who the oldest rider is...............me!
