Running is an integral part of Tarahumara culture. Barefoot Seeds founder Will Harlan has been running alongside the indigenous Tarahumara for over a decade. He is the 2009 champion of the Copper Canyon 50-Mile Ultramarathon.
Barefoot Seeds distributes corn seed from their annual harvests at Tarahumara running festivals. Tarahumara gather in the winter months to distribute corn seed from seed banks. They also run rarajipari, or ball-kicking races, which can last for days and span 100 miles or more. Tarahumara run in teams representing each village and work together to kick a heavy wooden ball across rocky, rugged canyon terrain. Women also run ariweta, a long-distance running race that involves flinging a wooden ring with a stick while running dozens of miles.
