The ride into Jefferson will be a true test of cyclists' conditioning, with 5,600 feet to climb over 83 miles. The route resembles a pastrami sandwich: Imagine two pieces of bread, flat on either end, with mounds of meat in the middle. As riders approach Jefferson they'll see what looks like a grain silo on the horizon. It is not. It is a 162 foot bell tower. Anyone who's not too tired from the 14.5 mile Karras Century Loop can ascend the 18 flights of steps to the top. Me? I'll take the elevator.by agreiter
