When ultramarathons are routine
There is a group of people called the Tarahumara living in Mexico who are well known for their long distance running.
The statement that, “The Tarahumara may be the finest natural distance runners in the world”, made by University of Arizona archeologist Michael Jenk inson, offers some insight into just how good the indians are at running. The Tarahumara routinely run distances only covered by only the most advanced ultramarathon runners today. … While on foot, the Tarahumara do not stroll from one place to their destination, running is used to perform everyday tasks. It is not uncommon for a Tarahumara to travel between fifty and eighty miles everyday at a “race” like pace.
Tarahumara running is based on endurance not speed. This fact is exemplified by their hunting practices. In order to catch such wild animals as deer, wild turkeys, and rabbits, the Tarahumara simply chase after the animal until the animal drops from exhaustion. Their hunting practices are widely known in Mexico and ranchers have been known to hire the indians to chase down wild horses. It is also said that a Tarahumara once ran six hundred miles in five days to deliver a very important message.
