Sierra Nevada Trails Pinos Genil is a mountain marathon held in Pinos Genil, a village in Spain’s Sierra Nevada region, with a listed race distance of 46 km. It takes place in late October and holds a UTMB Index 50K classification, placing it in the long trail-race category, not a road-marathon format.
The challenging aspect is the ascent: the course includes 3,100 meters of elevation gain over 46 km. The results indicate a modest field, with 56 finishers, and the winning time was 6 hours 44 minutes, reflecting the terrain rather than a flat-distance comparison.
