Men of the Raramuri Tribe of Mexico, also known as the Tarahumara, are maintaining one of their oldest traditions: foot races of up to 100 miles across the Sierra Madre mountains.

The races are held every few weeks and draw intense competition and wagering. Teams of 10 racers from different Raramuri villages run for a day and a night until they finish or their opponents get tired.

Anthropologists and tribal members say the tradition is in danger due to modern influences, substance abuse and evangelical Protestants. Races among Raramuri have already become less common.
