The Appalachian Trail runs over 2,000 miles miles from Maine to what southern state?

The Appalachian National Scenic Trail, generally known as the Appalachian Trail or simply the A.T., is a marked hiking trail in the Eastern United States extending between Springer Mountain in Georgia and Mount Katahdin in Maine. The trail is about 2,200 miles (3,500 km) long, though the exact length changes over time as parts are modified or rerouted. The Appalachian Trail Conservancy claims that the Appalachian Trail is the longest hiking-only trail in the world. More than 2 million people are said to do at least one day-hike on the trail each year.

An extension known as the International Appalachian Trail continues northeast, crossing Maine and cutting through Canada to Newfoundland, with sections continuing in Greenland, through Europe, and into Morocco. Other extensions continue the end of the Appalachian range in Alabama and continue south into Florida, creating what is known as the Eastern Continental Trail.

A thru-hike generally requires five to seven months, although some have done it in three months, and several trail runners have completed the trail in less time. Trail runners typically tackle the AT with automobile support teams, without backpacks, and without camping in the woods. The current speed record for a self-supported (meaning no vehicle or crew support, implying carrying a heavy backpack) thru-hike was set by Heather "Anish" Anderson. She completed the trail, southbound, on September 24, 2015, in 54 days 7 hours and 48 minutes.
