Oso Negro ® Ultra Trail 50K

$ 1800

The Ultra Trail Oso Negro® 50K will take place on January 15, 2022 and the appointment is at 5:00 a.m. El Barrial, Villa de Santiago, Nuevo León.

This Ultra Trail del Oso Negro is a one-of-a-kind race since it represents a physical and mental challenge when ascending through paths and trails to La Chancaca in the Sierra de Santiago, Nuevo León. Some points very similar to 100k, the scenery and forests are spectacular.

The competition begins in the town of Santiago Pueblo Magico, Nuevo León on paths, without paved roads and dirt roads with little vehicular traffic. From Barrial we take the route to Chancaca, Batea, San Cristobal, Los Chorros, Pico del Indio and Tinajas and we descend through Batea to Barrial to reach the goal.
