Warren Doyle

Warren has been criticized for what some describe as a disobedient attitude toward rules & regulations. In the 1990s, the Appalachian Trail Conservancy removed a bathtub he had placed in a stream in Virginia near I-77. Warren has led his groups to cross the Kennebec River by fording, a practice the Maine Appalachian Trail Club says is dangerous as the volume of water flowing in the river can increase rapidly when an upstream dam is opened.

Since 1989, approximately one thousand hikers have completed Warren's Appalachian Trail Institute, a five-day long training course taken by those who hope to complete a thru-hike. According to Backpacker magazine, about 75% of those who complete this course go on to complete a through hike. This is substantially higher than the 20% - 25% of those who start on a hike who actually finish the entire trail in one year, as reported by the Appalachian Trail Conservancy.

In winter 1979, following an act of civil disobedience, Warren was arrested at Baxter State Park for climbing Katahdin, the terminus of the trail. As a matter of conscience, Warren chose to spend a night in jail rather than pay a $25 fine to raise awareness for what he thought was an unnecessary policy. Sometime after the incident, the Baxter State Park authorities changed the policy and allowed climbing of Katahdin in the rain.

Warren's interest in the Appalachian Trail was such that he organized a group of mostly college students to hike the trail in 1975. All 19 participants in the group completed the hike together in 109 days. Warren led additional "Circle Expeditions" of the Appalachian Trail in the years 1977, 1980, 1990, 1995, 2000, 2005, 2010; (also with phenomenal completion rates); and then two 'regular' expeditions in 2015 and 2017."THE 2017 APPALACHIAN TRAIL EXPEDITION" (PDF) . </ref>

Warren Doyle is a hiker and supporter of the Appalachian Trail. He holds the informal record for the hiking the entire Appalachian Trail the most times (eighteen times; 9 thru-hikes and 9 section hikes). From 1974 to 2017, as a labor of love, he organized and led 10 groups up the entire Appalachian Trail with a superlative completion rate. He is the founder of two organizations dedicated to the trail: the Appalachian Long Distance Hikers Association, and the Appalachian Trail Institute. He remains the Director of Appalachian Trail Institute.

Warren Doyle (born 1950) became interested in hiking while attending Southern Connecticut State College. He had spent one summer after his junior year volunteering in the mountains of Jamaica and the next near the coalfields of southwest West Virginia; the latter enabled him to meet, and be mentored by, the noted Appalachian activist/educator/poet Don West. In 1973, he decided to hike the Appalachian Trail solo, and in doing so in 66 days, set the unofficial endurance record for the then-fastest hike. Doyle has two children., and is divorced. He went on to become an American Studies Professor at George Mason University and the founding director of that institution's Hemlock Overlook: Center for Outdoor Education Center (1985–96). From 2004-2010, he taught at Lees-McRae College in Banner Elk, North Carolina.
