The Ultra Maratón Caballo Blanco (also known as the Copper Canyon Ultramarathon, CCUM, or Ultra Caballo Blanco) is a 50-mile ultramarathon held annually in the town of Urique, in the northern Mexican state of Chihuahua.
[1] The event was recognized internationally as the Copper Canyon Ultramarathon through author Christopher McDougall's book Born to Run.
What started with a few local Tarahumara athletes now annually attracts over 1200 endurance runners from over 20 countries.
These age based races for younger runners take place on Saturday and are surely a highlight of the week.
In addition to helping continue the running traditions with the youth, the events also support the kids with a party, and donations from sponsors and the community to make for a day these young ones look forward to all year long.
