II PULMÓN DE ACERO TRAIL 2026

Experience the PULMÓN DE ACERO TRAIL, an exhilarating circular route that takes runners through some of Barakaldo's most iconic hills. This trail offers breathtaking panoramic views and challenging terrain that will test even the most seasoned athletes.
The journey begins in Retuerto, where you'll start your ascent towards Monte Goronillo (274 m), marking the first significant climb of the day. After conquering this initial peak, runners proceed to Santa Lucía before tackling the formidable summit of Monte Argalario (514 m). Atop this mountain lies a rewarding view and a sense of accomplishment as you approach your main objective.
From here, it's onwards toward Pico Mendibil (549 m), famous for its distinctive communications tower known locally as "Pirulí." This landmark signals the halfway point in terms of elevation but not necessarily distance or effort. After reaching this summit, participants will navigate through Peña Mora before beginning a descent that still includes several undulating sections to keep runners engaged.
The return route features a technical downhill passage across Monte Goronillo's slopes and leads you towards "Txokos," an area rich in local culture and heritage. The final stretch takes you along Bengolea’s winding paths, culminating at the finish line back where it all began—Parque Tellaetxe.
This event is tailored for runners who seek a technical challenge amidst natural beauty: relentless climbs, rocky descents, and a series of peaks that reward your efforts with stunning vistas. The PULMÓN DE ACERO TRAIL offers an immersive experience in terms of scenery, elevation gain, and sheer enjoyment.
The route's diverse landscape ensures a unique blend of physical exertion and scenic beauty, making it ideal for those who appreciate the finer details of trail running. With its mix of steep ascents, technical descents, and breathtaking views, this race is not just about reaching the finish line but experiencing every moment along the way.
Whether you're an avid mountain runner looking to test your skills or someone drawn by the allure of Barakaldo's lesser-known peaks, PULMÓN DE ACERO TRAIL promises a memorable adventure in one of Spain’s most scenic landscapes.
