Trail du Mercantour 2026: complete FR + EN guide

The race requires two adaptations: running long in the mountains and handling possible Alpes-Maritimes heat. Climbs are long, descents technical and hydration can quickly become the limiting factor.

Saint-Martin-Vésubie gives direct access to the Mercantour, but it is still a valley destination. Transport, lodging and time margin must be organised before focusing only on training.

Prepare for the 80K with long climb blocks, rough descending and hot-weather runs. A good strategy alternates power hiking, economical running on flatter sections and very regular fuelling from the first hour.

Test your vest with two litres of water if the weather requires it. In the Mercantour, starting light can feel pleasant early and become unsafe if an exposed segment takes longer than expected.

The referenced 2026 listing gives 80 km and 5,200 m+ in Saint-Martin-Vésubie, with a late-June date. It is vertical enough to require real mountain experience.

The village is simpler with a car or booked transfer. If you come via Nice, avoid arriving very late: the valley still adds travel time after the plane or train.

The reference airport and train station are Nice Côte d'Azur / Nice-Ville. From Nice, reach Saint-Martin-Vésubie by car, carpool, regional bus or private transfer depending on available timetables.

For international runners, sleeping in Nice the night before is not ideal unless a very early shuttle is planned. The robust option is to already be in the valley the day before bib pickup.

Saint-Martin-Vésubie is the best base to limit start stress and stay close to the finish. Book early because valley capacity is limited.

Roquebillière, Venanson, Valdeblore or Nice can be backup options depending on car and timing, but every option adds a transfer constraint.

The Mercantour rewards patient runners: drink early, climb without ego, descend cleanly and keep real transport margin. Once Nice-to-valley logistics are under control, you can focus on the mountains.
