Chamonix is about more than just its legendary peaks, the Aiguille du Midi or the mountaineering routes that have shaped its international reputation. Throughout the year, the Mont Blanc valley also comes alive with major sporting, outdoor and cultural events that attract enthusiasts from all over the world.
For visitors, these events offer a chance to discover Chamonix from a vibrant, intense perspective, deeply rooted in mountain culture. For businesses, they also provide valuable inspiration for planning a corporate stay, a seminar, an incentive trip or an original team-building event in Chamonix, inspired by the valley’s unique energy.
Among Chamonix’s major regular events, three highlights stand out in particular: the Mont-Blanc Marathon at the end of June, the Arc’teryx Alpine Academy in early summer and the UTMB Mont-Blanc during the last week of August.

Why keep an eye on the events calendar in Chamonix?
Chamonix is a year-round destination, but certain times of year profoundly transform the atmosphere of the valley. The streets fill with runners, mountaineers, climbers, outdoor brands, support teams and spectators. The terraces come alive, the ski lifts are in high demand, accommodation is often fully booked and local businesses adapt their operations.
Knowing the calendar of major events in Chamonix therefore allows you to plan your stay in advance, book the right time slots and choose the period that best suits your objectives. A group seeking peace and quiet will not necessarily make the same choices as a company wishing to immerse its teams in the energy of a major sporting event.
For a corporate event, this local knowledge is essential. An expert in corporate events in Chamonix, such as Chamex Events, can assist companies in designing a programme tailored to the season, the participants’ level and the valley’s specific logistical constraints.
Late June: the Mont Blanc Marathon, a major trail running event in Chamonix
At the end of June, the Mont-Blanc Marathon truly kicks off the summer season in Chamonix. This iconic event brings together thousands of runners across several race formats, from the vertical kilometre (from the Centre to Planpraz) and the Duo Étoilé to longer distances, culminating in the famous 42 km marathon.
This event has become a must for trail running enthusiasts, but also for anyone wishing to experience the sporting atmosphere of Chamonix at the start of summer. The routes offer spectacular views of the Mont Blanc massif, the Aiguilles Rouges and the balcony trails overlooking the valley.
An ideal time to discover Chamonix through outdoor activities
Late June is a particularly appealing time of year. The days are long, temperatures are becoming pleasant, and the mountains are bustling with activity once again after the off-season. It is also an ideal time to organise outdoor group activities: hiking, orienteering, nature challenges, via ferrata, rafting, mountain biking or team-building workshops in the mountains.
For companies, the Mont Blanc Marathon can serve as an inspiring backdrop. It embodies strong values: pushing oneself to the limit, managing effort, mutual support, anticipation and adapting to the terrain. These themes naturally resonate with the objectives of a professional seminar or a mountain team-building event.
Early July: Arc’teryx Alpine Academy, the alpine spirit at the heart of Chamonix
At the start of summer, Chamonix also hosts the Arc’teryx Alpine Academy, an international event dedicated to mountaineering, climbing, mountain safety and outdoor activities. Chamex coordinates the entire event in partnership with Arc’teryx. Technical workshops, meetings with athletes, guided outings, conferences and activities generally punctuate this event, which is highly appreciated by mountain enthusiasts.
Unlike a purely competitive event, the Arc’teryx Alpine Academy emphasises knowledge-sharing, learning and experience. It is aimed as much at experienced practitioners as at those wishing to improve their approach to high-altitude mountaineering.
An event in keeping with Chamonix’s identity
Chamonix is one of the world’s cradles of mountaineering. The Arc’teryx Alpine Academy therefore fits perfectly with the valley’s DNA: a mountain culture that is demanding, technical and committed, yet also focused on sharing knowledge.
For a group or a company, this period can be an excellent source of inspiration. Without necessarily taking part directly in the event, it is possible to build a programme around the alpine world: supervised introductions, safety workshops, glacier exploration, scenic hikes, conferences on risk management or original outdoor activities.
Companies wishing to move away from traditional formats can draw on original team-building activities in Chamonix to create a memorable experience, consistent with the spirit of the destination and tailored to the participants’ profile.
Last week of August: the UTMB Mont-Blanc, Chamonix’s most famous trail running event
It is impossible to mention major events in Chamonix without talking about the UTMB Mont-Blanc. Held every year during the last week of August, this event has become one of the most prestigious gatherings in the world of trail running.
For several days, Chamonix becomes the international capital of trail running. Runners from many countries gather to take part in various races around the Mont Blanc massif, crossing France, Italy and Switzerland. The finish in the centre of Chamonix is one of the event’s most memorable moments, with a lively, intense and deeply moving atmosphere.
A week of huge crowds in the valley
The UTMB completely transforms Chamonix. The event attracts not only runners, but also their support teams, the media, outdoor brands, volunteers and a large public. Accommodation fills up very early, restaurants are in high demand and traffic in the valley can be heavier.
To organise a stay in Chamonix during the UTMB, planning ahead is essential. This applies to individuals, but even more so to professional groups. Bookings for accommodation, transport, catering and activities must be coordinated with precision.
This high volume of visitors can be a challenge, but also an opportunity. For a company, experiencing Chamonix during the UTMB means immersing its teams in an exceptional atmosphere, driven by effort, solidarity and collective emotion. The event can add a real highlight to a corporate trip, provided it is well prepared.

Organising a group trip during major events in Chamonix
Major events in Chamonix offer an exceptional setting for organising a group trip. They allow you to add depth to a programme, create a strong sense of local immersion and make the experience a defining moment in the life of the valley.
However, these periods require meticulous organisation.
Accommodation availability, travel arrangements, activity timetables and the management of free time must be planned in line with the crowds and the pace of the event. This is where the expertise of a local agency really comes into its own.
Chamex Events supports companies in designing bespoke corporate trips to Chamonix: seminars, incentives, team-building events, group ski trips or outdoor experiences. Thanks to its knowledge of the region, the agency can offer a programme that strikes a balance between work time, exploring the valley and group activities tailored to the group’s level.
An event such as the Mont Blanc Marathon, the Arc’teryx Alpine Academy or the UTMB can thus serve as an inspiring theme, without necessarily imposing a programme focused solely on competition. The aim is rather to harness the energy of the moment to create a memorable, unifying and well-organised experience.
What is there to do in Chamonix outside of events?
Even when major events are not taking place, Chamonix remains a leading destination for summer group breaks. The valley offers an exceptional playground for organising activities such as hiking, multi-activity challenges, glacier exploration, high-altitude evenings or unique experiences. In winter, group ski breaks are very popular, particularly the descent of the Vallée Blanche, ice climbing or ski touring.
For a seminar or team-building event, Chamonix’s appeal lies in the diversity of its options. You can tailor a stay to be sporty, contemplative, premium, adventurous or more accessible, depending on the company’s objectives. This flexibility allows the programme to be adapted to very different teams, with varying levels of fitness.
Major events therefore serve as useful markers on the calendar, but they are only part of the Chamonix experience. The real challenge lies in choosing the right time of year, the right format and the right balance between inspiration, team spirit and logistics.
Other unmissable events in Chamonix throughout the year
Beyond the major sporting events that define the summer, Chamonix also hosts several regular events that play a significant role in the valley’s appeal. Cultural festivals, international competitions and winter activities round out the calendar of highlights throughout the year.
July: the Cosmojazz Festival, concerts with a view of Mont Blanc
Usually held at the end of July, the Cosmojazz Festival has become one of Chamonix’s most unique cultural events. Conceived by musician André Manoukian, this festival offers open-air concerts in spectacular natural settings: mountain pastures, high-altitude panoramas or clearings accessible on foot or by ski lift.
The atmosphere is particularly friendly, bringing together jazz enthusiasts, mountain lovers and visitors seeking unique experiences. For a group holiday or a summer seminar, this period offers an inspiring setting that breaks away from traditional formats.
July: the Climbing World Cup, a sporting spectacle in the town centre
Every summer, usually in July, Chamonix hosts a round of the Climbing World Cup. The event brings together the world’s best climbers in disciplines such as lead climbing and speed climbing.
Set in the heart of Chamonix, the competition attracts a large crowd and temporarily transforms the town centre into a veritable open-air stadium. Even if you’re not a climbing enthusiast, the atmosphere is well worth a visit.
This event perfectly illustrates the sporting and international identity of the Mont Blanc valley.
June: Chamonix Film Festival, mountain cinema in the spotlight
The Chamonix Film Festival, usually held at the start of summer, showcases films about adventure, exploration, mountaineering and outdoor sports. Documentaries, preview screenings, meet-and-greets with athletes or directors, and talks offer a different way to discover the world of the mountains.
This more intimate event particularly appeals to outdoor enthusiasts and visitors seeking a cultural experience to complement the valley’s sporting activities.
December: Christmas markets and winter events in Chamonix
As the festive season approaches, Chamonix takes on a new atmosphere. From December onwards, the Christmas markets and winter events create a warm and welcoming atmosphere in the town centre. Illuminations, concerts, craft stalls, local specialities and festive events all contribute to the experience.
This period attracts both holidaymakers and corporate groups looking to organise a winter break or a skiing trip in a particularly lively setting. With skiing, Savoyard cuisine, visits to the Christmas village and team-building activities, December is a highlight for discovering Chamonix in a different light.
