Trail Minero El Calderín 2026

Trail Minero El Calderín is a 10 km mountain race and walking event in Torre del Bierzo, León, Spain. Held in February, it features separate starts for walkers and runners, beginning at Mina del Oro. Fundación Cultura Minera organises the event, open to adults. Its simple format suits those seeking a short, hilly trail outing over a long mountain ultra. The course uses an old path once travelled by local miners, defining the race's identity. It ascends 450 metres to a high point of 934 metres above sea level; the distance is modest but the elevation gain is significant. The route combines landscape views with mining history. The finish area maintains a social atmosphere with trophies and a post-race meal.
