Trail running

The Chamonix valley calls itself "the valley of trail running": the Marathon du Mont-Blanc takes place here at the end of June, and the UTMB starts and finishes here at the end of August. With a qualified professional, you can discover its trails at your own pace, from your very first outing to preparing for a race.

Trail running in Chamonix

Trail running is simply running on mountain paths: you run on the flat and the downhills, and walk the steep climbs. In Chamonix, the trails lead from the town centre into the forests, along balconies facing Mont-Blanc and up to the high passes. Every summer, the valley hosts the Marathon du Mont-Blanc at the end of June and the UTMB at the end of August.

Why head out with a pro?

They choose the route to suit your level and the weather, and take you on trails you wouldn't have found on your own. They help you work on your technique: getting going again on the climbs, placing your feet on the descents, using poles and pacing your effort at altitude. If you're training for a race, tell them, and they'll tailor the outing to your goal. On PEAKED, each pro lists their qualifications and outings on their profile.

What level do I need?

You don't need to have run in the mountains before. You just need to be comfortable running for a while without stopping: the pro will adapt the distance, the ascent and the pace. Experienced trail runners tend to come to improve their descending or to prepare for a target event. When you message the pro, let them know what you're running at the moment.

When should I go?

From late spring to autumn. The lower trails can be run from spring onwards. Higher up, snow can linger late depending on the winter, so the pro will choose the route based on snow conditions. Autumn, cooler and quieter, is also a very good season.

What should I bring?

Trail running shoes, a windproof and waterproof jacket, water and something to eat, carried in a small rucksack or a running vest. Depending on the route, the pro will tell you whether you need poles or a warm layer. For full details, see our complete trail running kit list.
