Specifics of mountain running

Summer mountain or winter mountain, there is no season to discover mountain running. But don't forget that topography plays a significant role, as the changing terrain includes many elements that increase the difficulty of the course (stones, puddles...). The weather is an essential factor, especially because the temperature sometimes drops rapidly. While this physical activity provides well-being and a sense of freedom, it should also not be forgotten that this sport is intended for healthy people with good cardiovascular capacity.

  • Mountain Races : These are races of about 1 hour, with a minimum elevation gain of 500 meters.

  • Green Races : Quite easy, they measure a maximum of 30 kilometers and are suitable for many runners.

  • Trail: Running races practiced in nature or on trails, mountain trails are characterized by a significant elevation gain. There are short trails (from 20 kilometers) or, conversely, extremely long ones (over 70 kilometers, ultra-trails).

Equipment needed for mountain running and trail running

Of course, sunscreen, sunglasses and a cap (or hat if it's very cold) are essential for mountain running. Here are the main tips from Sport 2000's trail and mountain experts:

  • If you are running on relatively flat trails, you can use your classic running shoes, as long as they have good ankle support and are sufficiently waterproof. However, if it is a rugged course with a strong elevation gain, take shoes specially designed for trail running (thick sole with strong grip, capable of crossing mud or snow). Also choose a shoe according to your weight, with adequate cushioning (limited cushioning only for people under 80 kilograms; more pronounced cushioning for others, with back problems or for running very long distances).

  • Opt for models designed for mountain running or trail running (with a high upper to better protect you from impacts), but also shoes that are sufficiently grippy and waterproof, regardless of the weather conditions, while allowing your foot to breathe.

  • Wear breathable synthetic clothing, to better wick away moisture. Bring a light jacket in case of bad weather, both waterproof and sufficiently warm.

  • You also need a backpack that is not too bulky (15 liters maximum if you are running an ultra-trail).

  • Invest in a headlamp for running at night and a safety blanket.

  • Finally, carry your water in a practical water bottle (possibly in a water bottle belt) and bring a mobile phone (for emergencies) during your mountain run.

Note that if you plan to participate in an organized race, certain equipment is mandatory, as is the medical certificate to be provided during registration. Remember to consult the list of mandatory equipment before starting.

Some mountain running routes

The French mountains offer a multitude of routes, more or less difficult. In the Alps, the Pyrenees, the Jura, the Massif Central or the Vosges, you will find something to enjoy, while admiring the surrounding nature.

Mont-Blanc Marathon

If the mountain marathon requires more effort than on flat terrain, the beauty of the panorama should make you forget the difficulty of this high-altitude course.
Does the distance of this race scare you? You can run only 10 or 23 kilometers...or conversely, run a distance of 90 kilometers.
And if you want even more, the UTMB (Ultra Trail du Mont-Blanc), which takes place every year starting from Chamonix, is a 171-kilometer trail, with 10,000 meters of positive elevation gain. A real challenge, reserved for experienced runners!

Maxi-Race

This race takes place around Lake Annecy, a town close to renowned resorts such as Le Grand-Bornand or La Clusaz. The Maxi-Race events alternate between distance or timed challenges and can be run alone or in a team. The shortest route is 16 kilometers, the longest 110 kilometers.

The Grand Raid des Pyrénées

A classic of mountain running, the interest of the Grand Raid des Pyrénées is to be able to run between 40 and 160 kilometers to discover the Néouvielle nature reserve.

La Flégère

Ideal for beginners, this trail is accessed by chairlift. La Flégère has the advantage of combining glacier views with a route with little elevation gain.

Les Portes de Cristol

The start of the Portes de Cristol trail is located in Serre-Chevalier, in the Hautes-Alpes. An opportunity to admire Lake Cristol and the spectacular view of the Écrins massif, covering nearly 1000 meters of positive elevation gain.

L'Espace Haut-Jura Trail

The Alps and the Pyrenees are not the only massifs suitable for mountain running. Several areas are set up in the Jura mountains, including the Haut-Jura Trail. You will find 21 routes, ranging from easy to difficult, with also the possibility of running a vertical semi-kilometer from Saint-Claude and a vertical kilometer from Septmoncel – Les Molunes.
