It is a one-of-a-kind race as it represents a physical and mental challenge when entering the Sierra of Santiago. The views and landscapes, throughout the entire race, are also a great attraction, so it is recommended to bring an action camera. This route is located 35km from downtown Monterrey (MTY).

The competition begins in the town of Santiago Pueblo Magico, Nuevo León on sidewalks, few paved roads (only 7kms) and dirt roads with little vehicular traffic. From the starting point we take the Barrial route, ascending to La Chancaca then descending to San Cristobal from there we hike to El Manzano through gaps and sidewalks, reaching the CP, we begin another intense ascent meters to the place known as La Cienega to continue advancing through Sierra Mauricios, descent to the "middle pass"

With scenes of forests, rivers, mountains and the best landscapes of the Sierra de Nuevo León passing through the mountain communities of Santiago, San Cristobal and Cienega de Gonzalez.
