The Manitou Incline, near Manitou Springs, Colorado, was constructed as a funicular in 1907. It operated until 1990, when a rock slide washed out the rail bed. Since then it has been used for hiking, and has become a very popular test piece for endurance athletes. The Incline starts at 6600 feet elevation and gains 2000 feet in roughly a mile. The old railway ties form many steps along the route.
