Transcandamia is a trail-running series in León, Spain, with races held at the start of the year. The event offers short and middle-distance options, including a 12 km trail and a 23 km trail, and its own website describes it as a different kind of race to begin the running year.
The longer race has drawn strong mountain runners, with past 23 km winners including Oihana Kortazar and Javier Domínguez, while the 15 km race has been won by Itamar Sutil and María Frey. The organizers publish official classifications, photos, and video after the event, share real-time updates through a WhatsApp channel, and provide registration and streaming information through the event platforms.
