The word for themselves, Rarámuri, means “runners on foot” or “those who run fast” in their native tongue according to some early ethnographers like Norwegian Carl Lumholtz, though this interpretation has not been fully agreed upon. With widely dispersed settlements, these people developed a tradition of long-distance running up to 120 miles (190 km) in one session, over a period of two days through their homeland of rough canyon country, for intervillage communication and transportation as well as to hunt. [2] The Tarahumara also use the toe strike method of running, which is natural for bare-footed runners. The long-distance running tradition also has ceremonial and competitive aspects. Often, male runners kick wooden balls as they run in “foot throwing” competitions, and females use a stick and hoop. The foot throwing races are relays where the balls are kicked by the runners and relayed to the next runner while teammates run ahead to the next relay point. These races can last anywhere from a few hours for a short race to a couple of days without a break. Pre-tool humans may have used persistence hunting universally to hunt prey. Humans in excellent physical shape, given the time, can outrun quadrupeds, which slow down when fleeing over long distances and lose their ability to pant while running.
