This study found that in Morgantown, West Virginia, one-quarter of trail users had not been active before the trail was built, and who report large increases in physical activity since they began using the trail. For most of these newly-active residents, the trail was the only place where they exercised and they report the trail’s safety, paved and flat terrain, and convenience as the most important considerations in deciding to use the trail.
