2KV Collarada is a mountain running series held in Villanúa, Huesca, within the Spanish Pyrenees. The primary event is a demanding 17 km up-and-down race featuring 2,016 meters of elevation gain and descent. Additionally, the series offers a Vertical Kilometer, a shorter race exceeding 5 km with over 1,000 meters of ascent. Organized by Club 2KV Villanúa, the races operate under International Skyrunning Federation guidelines, aligning them with skyrunning principles rather than standard trail running.
The course navigates around Collarada, the prominent mountain overlooking Villanúa. Some race finishes are positioned near the 2,000-meter mark, while other formats connect to the 2,886-meter summit. Local race designations, such as “Puyar Nomás” (uphill only) and “Puyar y Baxar” (uphill and downhill), clearly convey the race objectives. Typically, fields range from approximately 300 to nearly 400 participants across all categories. The event often combines multiple high-caliber races in a single day, including championships for the Spanish Vertical Kilometer and open international vertical competitions. Given the mountain environment, race organizers have previously adjusted course lengths due to unpredictable weather, highlighting the challenging nature of the terrain.
