The Rarámuri or Tarahumara are a Native American people of northwestern Mexico who are renowned for their long-distance running ability. Rarámuri, means "runners on foot" or "those who run fast". Staple crops are corn and beans.
Frugan (fruitarian) runners Tarahumara were described by Ruth Heidrich, Ph.D., a runner for 36 years and vegan for 21 years, who won over 800 age-group first place trophies in runs, triathlons, biathlons, and track and field, and completed the Ironman Triathlon 6 times, run 67 marathons, and holds a number of fitness records, following a diet similar to the Tarahumara:
"...Their only food is tesguino, milled corn mixed with water to a drinkable consistency. This is the mainstay (75%) of Tarahumara diet, with the remaining food being beans and squash. They also take the milled corn as their sole food when traveling, since it is lightweight, doesn't spoil, and is easily prepared by mixing it with water in a half gourd they carry with them. This gives them great stamina and, more importantly, none of them appeared to be protein or calcium deficient with this plant-based diet."
The Tarahumara runners are legendary for their 24-, 36-, even 72-hour long runs. In the Leadville 100-miler in 1991, the Tarahumara took first, second, and fourth places.
