La Transvolcanique: The MTB Adventure in the Heart of the Volcanoes

Since 1992, La Transvolcanique has been a must-attend event for MTB enthusiasts in France. Organized by the cycling section of the Foyer Rural de Blanzat, this associative tour has the modest but firm ambition of showcasing the magnificent Auvergne region by mountain bike, in a friendly and good-natured atmosphere.

An Exceptional Route Through the Volcanoes

The La Transvolcanique route is one of the most beautiful MTB itineraries in France. Over two days, participants cross the Regional Natural Park of the Auvergne Volcanoes, mostly using unpaved paths:

  • Day 1: Blanzat → Mont-Dore, approximately 85 km through the Chaîne des Puys and the Sancy massif
  • Day 2: Mont-Dore → Blanzat, return via a different route

Longer variations are offered for the most seasoned cyclists, with GPS navigation using GPX tracks provided by the organization.

Exemplary Volunteer Organization

La Transvolcanique is entirely organized by volunteers from the cycling section of the Foyer Rural de Blanzat. Registration includes course marking, several refreshment stops with a hot meal served at the table for lunch, luggage transport between departure and arrival, a souvenir gift, a free beer at the finish line, a prize draw, and a closing reception.

An Eco-Responsible Commitment

As an eco-responsible partner of the Regional Natural Park of the Auvergne Volcanoes, La Transvolcanique is committed to a waste reduction approach: reusable cups, recycling sorting, local sourcing, and encouragement of carpooling. The course layout is coordinated with the park's services and landowners' associations to ensure respect for natural spaces.

A National-Scale Event

With 1,000 to 1,600 participants each year, La Transvolcanique attracts mountain bikers from all over France and abroad, particularly from Belgium. It is recognized as the largest mass mountain bike event organized over two consecutive days, a unique format that allows for a true sporting and human adventure in the heart of the Auvergne volcanoes.
