Time is a constant, but I figure I'm working harder on the mtb so I thought if mtb miles converted to road miles, say Xmtb is = or <Xroad miles, I figured I had more gains on the road bike than the mtb. I was thinking along the lines of maybe the road gains were at least twice that of the mtb. This is beginning to sound like an algebraic word problem.
