Trail La Montagn’Hard 2026
A tough Mont Blanc trail weekend with big climbs, wild views and a family-friendly children’s race in Les Contamines.
La Montagn’Hard is not a gentle introduction to trail running. It is a proper mountain weekend, built around steep Val Montjoie trails, big views towards Mont Blanc, the Miage Glacier, the Beaufortain and the Aravis. Alongside the serious long-distance races, La Petite Hard’venture brings the same atmosphere into Les Contamines-Montjoie, with short, non-timed children’s races and a friendly village feel.
Bottom line: Trail La Montagn’Hard 2026 takes place from Saturday 4 to Sunday 5 July 2026, with race formats of 20km, 50km, 70km and 100km. La Petite Hard’venture takes place in Les Contamines-Montjoie on Saturday 4 July 2026, with free children’s races for ages 3 to 15.

Why this event is worth adding to your Les Contamines plans
This weekend gives Les Contamines and the Val Montjoie a strong summer trail-running atmosphere. The main Montagn’Hard races bring serious mountain runners into the area, while La Petite Hard’venture makes the event feel welcoming for families and younger runners.
The location is also part of the appeal. Les Contamines sits in a beautiful part of the Mont Blanc region, with access to alpine trails, traditional villages, mountain refuges and views that feel different from the busier Chamonix side of the massif.

Practical tips for race weekend
- Check the official runner guide: Race rules, mandatory kit and course details should be confirmed before travelling.
- Plan around two locations: La Petite Hard’venture is in Les Contamines village, while the main Montagn’Hard weekend is centred around the wider Val Montjoie / Saint-Gervais area.
- Arrive the day before: Early starts, bib collection and kit checks are much easier with a little extra time.
- Prepare for mountain weather: July can be warm in the valley, but conditions can change quickly on high trails.
- Bring layers for children: La Petite Hard’venture starts in the morning, and village temperatures can still be cool.
- Book transfers early: Early July is a busy period for Geneva Airport and the Mont Blanc region.
