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.
The best exercise to prepare for a hike is good, old fashioned walking. Walking provides both a cardiovascular workout and strengthens the same muscles you'll use on your hike. Begin by walking 30 to 45 minutes three days a week to train for a five mile (eight kilometer) hike. On a fourth day, take a longer walk and increase your distance each week until you're walking about two-thirds of the length of your hike [source: Spilner and Robertson ].
