Be aware that you'll be paying back your law school loans for years after graduation. Do you best not to overburden yourself with student loans--it could cause you considerable stress or even limit your career options. Look into location. Law school is tough enough without being isolated from family or living in a city that doesn't suit you.
What is Average? Hikers will vary in their conditioning, weight of gear, natural fitness, comfort range, and several other factors that influence hiking speed. With all these considered, most hikers will average about 2-3 miles per hour (3.2-4.8 km/h). Besides personal differences, different trails will have a huge impact on your hiking speed. Some trails are at a higher elevation, which decreases the amount of oxygen replenishing your muscles.
What is the Appalachian Trail? The Appalachian Trail (AT) is a National Scenic Trail extending from Springer Mountain, Georgia, to Mount Katahdin, Maine, and protected by federal- and state-owned lands as well as public rights-of-way. The trail measured 2,168.1 miles in 2001. The total distance of the trail changes slightly from year to year as trail maintenance groups reroute the trail as needed. An Appalachian Trail thru-hike takes between five and seven months to complete the entire trail. (About 20 percent of hikers who begin the trail will complete it.) The average cost of an Appalachian Trail thru-hike is approximately $3,000 (about $1.50 per mile), not including gear.
