Oso Negro 30K: Your gateway into Mexico’s toughest mountain race.
Built for runners looking to step up their trail game without compromising on the raw, unrelenting technicality that defines Oso Negro. This 30-kilometer course packs the full DNA of Sierra de Santiago into a punchy, demanding format: punishing climbs, dense pine-oak corridors, aggressive descents over loose scree and pine needles, and ridgeline trails delivering sweeping views of rugged canyons below. This is not a warm-up; it’s a true test of grit, power, and high-altitude technical agility.
