The famous "Cuesta del Ajoguillo"
Myth
The Cuesta del Ajoguillo is just another hill on the course.
Reality
It's where the winner is decided. Located at km 14, it is the steepest climb in the Medio Maratón San Blas.
Located around kilometer 14 of the route, runners have already covered a significant distance before facing this challenge. It is one of the steepest climbs on the course, and every runner respects it.
— Antonio Rodríguez, Executive Director of the Medio Maratón San Blas
Despite its reputation, there is no reason to fear the Ajoguillo. It is simply part of the unique San Blas experience.
Arrive between 2:00 and 5:00 a.m. There is no transportation after 5:00 a.m.
Use Route 153 as the main route. Route 14 will be closed from 8:00 p.m. on Saturday.
