Both the race staff and volunteers are what make it possible for the Black Bear Ultra Trail (UTON) to be the most spectacular race and with the most intense challenge of Mexico.
We believe that volunteering UTON will be an unforgettable experience, and a great opportunity to see places, friends and athletes.
If you want to visit the mountains of Santiago, Nuevo Leon and spend a fun weekend, we invite you to join the UTON! This might not be a reality without your help. THANKS!
