The Isasa Trail Xtrem is a trail running race around Arnedo (La Rioja), Spain's shoe-making capital and home of the Atom brand. With three distances from 16 to 46 km, it follows spectacular and lesser-known routes through the Riojan mountains, combining technical trails, ravines, and vineyard landscapes with views of the Sierra de Cebollera.
