The Triple Crown of Hiking informally refers to the three major U.S. long distance hiking trails:
The total length of the three trails is about 7,900 miles (12,700 km); vertical gain is more than 1,000,000 feet (300,000 m) (190 miles). A total of 22 states are visited if the three trails are completed The American Long Distance Hiking Association – West (ALDA-WEST) is the only organization that recognizes this hiking feat. At the ALDHA-West Gathering, held each fall, the Triple Crown honorees are recognized and awarded plaques noting their achievement. As of October 2011, 155 hikers have been designated Triple Crowners.
