Event Description

The UMCB has an incredible and storied history, and is recognized as one of the world's most recognized Ultras. Started by Micah True to bring runners from all over the world and introduce them to the Ramamuri (Tarahumara) people and their great culture. The Ultra event brings together endurance athletes from all over the planet to run together with over (what is typically) 600 Raramuri athletes. 

This year will mark the first year that a Marathon distance will be added. While the Marathon will allow more athletes who prefer to run this distance over the 50 Mile, it will still be a very challenging event. The course is being finalized and we are most excited. This will surely prove to be one of the most scenic Marathons on the planet.

Both Ultra and Marathon registrations include the races and attendance to the full weekend of cultural events, activities and gatherings.
