Ultra Marathon Caballo Blanco

The Ultra Marathon Caballo Blanco is conducted and coordinated by True Messages (a 501c3 nonprofit continuing the projects and messages of a simple messenger with a powerful message: Micah True el Caballo Blanco) along with the Municipality of Urique, Chihuahua with support from ‘Mas Locos’ throughout the world. The UMCB has an incredible and storied history and is considered one of Ultra Marathon Running’s must-do bucket list events. Started by Micah True who had a goal to bring runners from all over the world and introduce them to the Ramamuri peoples, their beautiful lands and their cultural traditions and wisdoms. The Ultra events bring together endurance athletes from all over the planet to run together with 600-800 Raramuri athletes.
Now also added last year is the ultimate endurance challenge a 100 Mile journey through the majestic Sierra Tarahumara! The 50 Mile Ultra remains one of the most iconic run in the Americas and the distance that most all of the Raramuri athletes will take on. The Marathon and Half are still a very very challenging run but you are rewarded by the beauty and magic of these lands and surely one of the most scenic runs on the planet.
All event registrations include the races and attendance to the full weekend of cultural stage events, activities and gatherings in Urique. Recognizing that the logistics of getting to the event and securing accommodations can sometimes present a challenge, again this year we have arranged with local businesses to offer ‘ALL INCLUSIVE’ type packages as well as help and support for getting to and from the Sierra Tarahumara and hotel/hostel/housing once you are there for race week(end). *SEE WEBSITE FOR DETAILS! These experiences introduce all that is special about the Barrancas, our Raramuri friends and the local communities of Urique and Cerocahui (hikes and runs with our Raramuri friends, sweat lodge / temezcal, Raramuri teachings, eco tours, etc) For details on the agenda and pricing click the “Website” link on this page above.
Also we would like to mention, while a separate event from the Ultra and Marathon events, a highlight of the weekend is the UMCB kids race on Saturday which features 800 young athletes in short races around the town of Urique. We ask that all of our runners join in and support the kids events and help continue this wonderful running tradition with the next generation!
Stay tuned on Social Media as many more updates for this coming March 2026 event will be forthcoming. As always it will be extra special and we have an incredible week planned! We all look forward to what is going to be an amazing event!
We expect the races to sellout this year. While the course can accommodate many runners, even with all we are doing to increase housing options, there are limitations – so please book early (with us or locally)!
*This is a ‘Korima’ focused event started by Micah to support the local and Raramuri communities. Your race registration helps with this greatly and we appreciate it. No refunds are provided however we can defer your entry to next year if requested before January 30th. In the event the race is cancelled by the organizers due to unforeseen circumstances, health or safety issues your registration will carry over and will be applied to the rescheduled event.
