Puerto Vallarta, Jalisco. The second Sierra Mar XCM Mascota-Vallarta mountain bike race will connect the highlands with the Pacific coast on Saturday, October 24, 2026. Its main 100-kilometer route starts in the Pueblo Mágico of Mascota and finishes in Puerto Vallarta.
The Puerto Vallarta Tourism Board and Visit Jalisco describe the event as an endurance ride through the Sierra Madre Occidental, with mountain trails, forest roads, and large elevation changes between Mascota and the coast. It is the second edition of a race that debuted in 2025.
This is a competitor-focused event rather than a casual recreational ride. The official listings direct riders to the Maratón Sierra Mar social channels for registration and current instructions. Visit Jalisco still marks the starting time as “to be confirmed,” so participants should check the organizer’s latest notice before arranging transportation or support. Spectators should also confirm accessible viewing points instead of assuming the full mountain course can be reached by road.
For visitors, the route is also a useful reminder that Puerto Vallarta’s surroundings change quickly from coastal scenery to mountain country. The site’s regional map of Puerto Vallarta and Jalisco’s Magical Towns offers more context for planning time in Mascota and the sierra.
