Their secret is Chia

The Tarahumara Indians are a tribe of superathletes.

For centuries the Tarahumara Indians have relied on chia, the ancient super food the Aztecs called “the running food”, to give them sustained energy and to keep themselves hydrated while they run distances that only the most advanced ultra marathon runners will attempt.
The Tarahumara are renowned as super runners.
Some say they are the best long distance runners in the world.
They play a running ball game that can last up to three days. Without stopping!
They race from village to village, covering distances over 150 miles for a fun, friendly competition.
They hunt by chasing their prey, including deer and rabbits, until the animals drop from exhaustion.
They carry only chia, in small pouches, to nourish themselves during these extreme endurance events.

Now you can get Running FoodTM—micro-milled chia seed—the all natural, whole food that can help you sustain your energy, and maintain your hydration while you train and compete.
