Greenways are corridors of protected open space managed for conservation and recreation purposes. Greenways often follow natural land or water features, and link nature reserves, parks, cultural features, and historic sites with each other and with populated areas. Greenways can be publicly or privately owned, and some are the result of public/private partnerships. Trails are paths used for walking, bicycling, horseback riding, or other forms of recreation or transportation . . . .

Many people realize exercise is important for maintaining good health in all stages of life; however, many do not regularly exercise. The US Surgeon General estimates that 60% of American adults are not regularly active and another 25% are not active at all. In communities across the country, people do not have access to trails, parks, or other recreation areas close to their homes. Trails and greenways provide a safe, inexpensive avenue for regular exercise for people living in rural, urban, and suburban areas.
