Sierra Mar XCM Returns to Puerto Vallarta: October 24, 100K Route

Mark your calendars for October 24, 2026, as the second Sierra Mar XCM Mascota-Puerto Vallarta mountain bike race takes place. This 100-kilometer route starts in the charming Pueblo Mágico of Mascota and concludes in Puerto Vallarta. For those who enjoy a good challenge, this is the event for you.

It's an endurance ride through the Sierra Madre Occidental, featuring mountain trails, forest roads, and significant elevation changes. The race will connect the highlands with the Pacific coast, offering both competitors and spectators a unique experience.

For participants, the official listings direct you to the Maratón Sierra Mar social channels for registration and updates. The starting time is still to be confirmed, so keep an eye on the latest notices from the organizers. Spectators should also confirm accessible viewing points, as not all sections of the mountain course are easily reachable by road.

For anyone exploring Puerto Vallarta's surroundings, this event serves as a reminder that the landscape changes dramatically from coastal areas to mountain regions. Check out the regional map on our site for more context on planning a visit to Mascota and the sierra.
