Hike the entire very strenuous Maryland Section of the Appalachian Trail in one day during the 3rd Annual MAHG 41 AT Trail Challenge!

People from across the globe are drawn to the AT for a variety of reasons; several are exemplary examples of the MAHG charity's mission: to reconnect with nature, to escape the stress of city life, to meet new people or deepen old friendships. Additional reasons people are often drawn to hike the trail are to experience a simpler life.

"The trail was completed in 1937 and is a unit of the National Park System. The AT is managed under a unique partnership between the public and private sectors that includes, among others, the National Park Service (NPS), the USDA Forest Service (USFS), an array of state agencies, the Appalachian Trail Conservancy, and 31 local trail-maintaining clubs." -Appalachian Trail Conservancy
