Anchorage Trail Systems span 578 square miles (930.2km) in the Municipality of Anchorage, Alaska, United States. The Municipality of Anchorage created the first set of trail systems for recreation in the late 1950s, not developing a system that was commuter friendly until the mid 1960s. The trails, which are used primarily for recreation and commuter traffic, are heavily utilized year round for walking, biking, and skiing. Many of the trail systems in place that connect the city of Anchorage in a commuter-friendly way were kick started by John "Jack" Roderick, the first mayor of the Municipality of Anchorage, who held office from 1972-1975.
