Here is more data from the road between Volvo Trucks N.A., Greensboro, NC and Tanglewood Park, Clemmons, NC in the 2009 Tour to Tanglewood for Multiple Sclerosis. When I make elevation profiles, I like to force x and y to 0 because it helps me see how hilly the event is more accurately. You can make almost anything look hilly by setting the y-axis max/min to the elevation max/min. To make it better, I should probably plot all events on a 110-mile scale or some such (considering Carolina Century at 102 is usually the most I'd try in a day), but I don't yet really like how that looks.
