Most of us like to think that one of the advantages runners have over other athletes, or, more simply stated, running has over many other types of aerobic exercise, is the simplicity and freedom of the sport. You really can run just about anywhere, and for free. I remember coaching a sailor during the Gulf War, who was 6-4 and weighed 185 pounds, and he maintained an 80-mile-per-week program for most of a year. This sounds reasonable enough for someone training for a marathon, but when you consider he was limited to doing all of his running on the deck of an aircraft carrier, treadmill running doesn’t seem quite so limiting after all.
