About This Race
The 73K sits at the technical heart of the Tenerife Bluetrail by UTMB lineup, bridging the gap between the 47K introduction and the 110K's summit challenge. This distance draws experienced mountain runners ready to engage with Teide National Park's volcanic complexity across multiple ecological zones, from coastal trails through fragrant Canary pine forests to the otherworldly high-altitude terrain surrounding Spain's highest peak. The course demands technical proficiency and careful energy management through sustained climbs and descents on volcanic rock, pumice fields, and exposed ridgelines. Runners navigate a landscape shaped by centuries of eruptions, where sharp lava formations and loose scree require constant attention to foot placement. The route's diversity—shifting from humid coastal air to the thin atmosphere above 2,000 meters—tests adaptability as much as fitness. For runners building toward longer mountain ultras or seeking a substantial challenge in a compressed distance, the 73K offers a proving ground that respects the terrain's technical nature without requiring the overnight logistics or extreme altitude exposure of the flagship race.
The route begins near sea level before ascending through established trails in the pine forests that characterize Tenerife's mid-elevation zones. As runners climb, the vegetation thins and the volcanic geology becomes increasingly dramatic, with views extending across the island and out to neighboring peaks when weather permits. The technical demands intensify in the upper sections, where the trail traverses lava fields and volcanic ridges that require focused navigation and sure footing on uneven, abrasive surfaces.
