The second annual Sierra Mar XCM Mascota–Vallarta 2026 mountain bike marathon will showcase the rugged backcountry, verdant pine forests, and dramatic peaks of Jalisco. Link two of the region's most celebrated destinations, this arduous 100-kilometer championship route kicks off in the historic Pueblo Mágico (Magic Town) of Mascota and concludes along the coastline of Puerto Vallarta.
Traversing the Sierra Madre Occidental, the race offers competitors an exceptional endurance test while giving spectators a front-row view of the extraordinary elevation changes—spanning from high mountain ridges down to the ocean—that establish this area as a premier outdoor adventure hub.
