The Mont Blanc Marathon is a semi-autonomous race. Semi-autonomy is defined as the ability to be self-sufficient between two refreshment points, in terms of food, clothing and safety equipment, enabling the runner to adapt to any problems encountered or predicted (bad weather, physical problems, injuries, etc.).
Only runners wearing visible bibs and duly checked have access to the refreshment stations.

The composition of the refreshment point will be sent to runners at a later date.

Any runner seen littering the course will be penalized. A large number of garbage cans are available at each refreshment station and must be used.
Individual assistance is only permitted 20 metres before and 20 metres after the refreshment stations. Outside these zones, assistance is forbidden, as is support during the race.

Specialty bean-to-cup coffee

Café shoukâ

Coffee has many health benefits. Rich in antioxidants such as polyphenols, it helps reduce cellular damage and inflammation. It also improves cardiovascular health by promoting blood vessel function and lowering blood pressure. In addition, coffee provides vitamins, minerals, macronutrients and dietary fibre, which help intestinal transit and improve digestive health.

A genuine natural stimulant, the caffeine contained in coffee has numerous health benefits. Thanks to its ergogenic properties, it optimizes muscle function and improves physical performance, mainly by blocking the action of adenosine on the nervous system. As a result, it increases awareness and concentration, reduces pain perception and improves muscular concentration. What's more, caffeine helps the use of fat for energy purposes, delaying the depletion of glycogen reserves. This prolongs the duration of physical activity and delays the emergence of muscular fatigue.

The aim is to find the optimum dosage to obtain results without discomfort. To start with, a dose of 3mg/kg is recommended, which can be increased to 6mg/kg or even 9mg/kg if well tolerated.

At Shoukâ, our specialty coffees are freshly roasted by us in our Chamonix-Mont-Blanc factory, using the bean-to-cup principle.

From Brazil, Colombia, Indonesia, Guatemala, Mexico, Costa Rica, Nicaragua, Ethiopia and Rwanda, our coffees are an invitation to travel to the heart of the terroirs and traceable plantations that promote sustainable and social farming practices. We have carefully tasted them and selected them according to their aromatic profile, so that you can discover a wide range of flavors and enjoy a unique tasting experience.

Shoukâ offers some fifteen specialty coffees, available in bulk or bags, in beans or ground on demand, guaranteeing optimal freshness.


Bean-to-bar chocolate bars

Tablette de chocolat Shoukâ

Like coffee, cocoa is rich in antioxidants such as flavonoids, a specific subclass of polyphenols. Known for their antioxidant and anti-inflammatory properties, they have beneficial effects on cardiovascular and brain health. Cocoa also provides essential minerals such as magnesium, iron, zinc and potassium, which are vital for muscle function, energy production and electrolyte balance. Finally, cocoa contains dietary fiber, which helps digestive health.

Composed of theobromine and phenylethylamine, chocolate can stimulate the production of endorphins and serotonin, which can improve mood and reduce stress and fatigue. So, depending on the individual and their consumption, chocolate can help improve sporting performance.

At Shoukâ, our bars are handcrafted in our Chamonix-Mont-Blanc factory, using the "bean-to-bar" principle.

Sourced from Tanzania, Ecuador, Brazil, Cameroon, the Philippines and Venezuela, our beans come from small, often organic, plantations, selected for their botanical variety and aromatic profile. We carry out all the manufacturing stages at low temperature to preserve the beans' nutritional and taste values: we roast, crush, grind, conch and temper each bar. These steps are carried out by our chocolatiers with the greatest care, using only organic products and no additives, lecithins or preservatives to satisfy your taste buds.

Brasserie du Mont-Blanc "At the summit by nature"

Discover the beers of the Brasserie du Mont-Blanc, top-fermented and balanced French beers. They are brewed with unique, pure, untreated water, which finds its source in the heart of the Mont-Blanc massif.

La Brasserie du Mont-Blanc has 60 employees, and produces its beers in France, near Chambéry.

Reduced CO2 emissions

Brasserie du Mont Blanc chose to locate in Chambéry to be at the center of a logistics hub, thus saving 600,000 liters of diesel or 1602T of CO2 compared to Chamonix, closer to Mont Blanc. Better for the environment.

Since 2018, employees have been provided with an electric bicycle for their home-work commute.

Waste recycling and recovery

Co-products are recycled in short circuits: spent grains (a co-product of malt wafers and cereals) and yeast are recycled as animal feed, representing 3,500 tonnes/year.

In terms of packaging, 50% of the brewery's volumes are returnable thanks to the sale of barrel. For glass, France has a recycling rate of 80%, i.e. 3 bottles out of 4.

Social commitments to two associations

Sylv'ACCTES helps build the forests of tomorrow by financing virtuous forestry initiatives that systematically have a positive impact on the climate, biodiversity and landscapes. In the Mont Blanc massif, a major action: renewing softwood forests.

Brasserie du Mont Blanc is a patron of the Ma Chance Moi Aussi association. Its mission is to help the most vulnerable children in disadvantaged neighborhoods. Support is provided from the age of 5, in the evenings after school, on Wednesdays and during half the school vacations.
