Climbing is only 55'/mile, which is moderately hilly when viewed that way. As a frame of reference, the 180K route of D2R2 has 15,900' of climbing, with 6,000 of that coming in the first 36.5 miles, and something like 70% of the route is not paved. I know I will never do that.
In any event, do what T-Horse suggests.
