Delaware trails · PennDel/Mason Dixon
A 2.9-mile out-and-back in Delaware, with 228 ft of climbing. Managed by the state.
The climbing leans toward the first third: 46% of the ascent falls between mile 0.0 and mile 1.0. It gives back about 211 ft along the way, so it rolls rather than climbing steadily.
