I am in flatland south-coastal Delaware and the only "hill" within many miles is the Indian River Bridge. It has about a 4% grade and the span is about 1/2 mile long, 1/4 each side. I would have to ride back and forth on the bridge approximately 75 times to get to 1 mile of elevation gain. That is certainly doable, though boring, even with the terrific views of the Atlantic, Indian River and bay, and the surrounding landscape. It has been a few years since I have ridden anywhere with climbing involved.
