Biking on Long-Distance Trails Act This bill establishes requirements related to long-distance bike trails. The Department of the Interior and the Department of Agriculture (USDA) shall identify not fewer than 10 long-distance bike trails that make use of existing trails and roads, and not fewer than 10 areas in which there is an opportunity to develop or complete such trails. Interior and USDA shall coordinate with stakeholders on the feasibility of, and identifying any resources necessary for, completing the development of the trails so identified; before identifying a trail or road as a long-distance bike trail, ensure that identifying a trail or road as a long-distance bike trail would not conflict with an existing use of the trail or road; and seek geographically equitable identification, development, and completion of long-distance bike trails.
