A summer shaped by sport in La Rosière
Races, cycling, trail running, fun formats and more demanding events all come together throughout the summer. The result is a programme that appeals not only to enthusiasts, but also to families, curious holidaymakers and anyone who simply wants to enjoy the atmosphere.
La Rosière Bike Week: a week to discover cycling in the mountains
From 29 June to 3 July 2026, La Rosière Bike Week opens the summer season with a week entirely dedicated to cycling.
The idea is not only to bring together experienced riders, but also to help people discover different disciplines in an accessible and friendly setting. Downhill mountain biking, electric mountain biking, road cycling and bike trial all feature during the week, creating plenty of opportunities to try, watch, learn and share around cycling in the mountains.
Last Man Riding: an endurance challenge in an exceptional setting
On 4 July 2026, La Rosière hosts Last Man Riding, a distinctive event in the summer calendar. Its original format is based on a simple principle: riders set off every hour on the same circuit until only one participant remains in the race. It is a demanding challenge, of course, but also a powerful human experience, and one that can also be enjoyed from the sidelines, soaking up the atmosphere and supporting the riders in an outstanding mountain setting.
The La Rosière Trail: several formats so everyone can find their race
On 17 July 2026, the La Rosière Trail returns for its 11th edition.
One of the strengths of the event is the variety of distances on offer, allowing everyone to choose a format that matches their level and ambitions. Three adult races are available:
- 43 km – 3000 m elevation gain
- 22 km – 1450 m elevation gain
- 15 km – 800 m elevation gain
Children also have their own moment with La Rosière Game, an obstacle race designed in a fun and playful spirit.
The trail becomes an event that can be enjoyed just as much by taking part as by supporting others or simply enjoying the atmosphere on site.
MDS Crazy Loops: a sporting, inclusive and collective event
From 17 to 19 July 2026, La Rosière also welcomes back MDS Crazy Loops.
The event is built around a strong and simple idea: turning the mountains into a shared space, open to different profiles. Able-bodied athletes and wheelchair teams come together in a bivouac atmosphere around an accessible loop that can be completed freely over 24 hours.
It is an event that shows how mountain sport can also be collective, inclusive and deeply human.
La Bernardette: a cycling climb in an iconic setting
On 6 September 2026, the cycling event La Bernardette will link Séez to the Col du Petit-Saint-Bernard.
It is a highlight for cycling enthusiasts, but also a fine end-of-summer event that showcases one of the area’s most emblematic climbs.
Weekly events to enjoy summer differently
Summer in La Rosière is not limited to the major events.
Every Tuesday, the Rosière Fun Race offers a fun 3 km race in a sporting but relaxed atmosphere. It is an accessible format designed above all for enjoyment.
Every Friday, a cycling climb starting from Séez offers another way to experience the pleasure of effort in the mountains, in a superb setting.
These regular events bring rhythm to the season and make it easy to take part, even during a short stay.
An active summer, without pressure
What makes summer in La Rosière so appealing is precisely this balance: offering real sporting events while keeping the atmosphere accessible and friendly.
You can come to take part, to try something new, to watch, or simply to enjoy the energy of the resort. It is this openness that makes the summer programme so enjoyable.
La Rosière Bike Week runs from Monday 29 June to Friday 3 July 2026. It is dedicated to discovering several types of mountain cycling, including downhill MTB, e-MTB, road cycling and bike trial.
The Last Man Riding format, taking place on 4 July 2026, is demanding and requires strong endurance. However, the event can also be enjoyed as a spectator, to discover the atmosphere of this ultra-distance challenge.
The La Rosière Trail, held on 17 July 2026, offers three adult formats: 43 km, 22 km and 15 km. A children’s obstacle race, La Rosière Game, also takes place in the afternoon.
Yes. During the summer, the Rosière Fun Race takes place every Tuesday as a fun 3 km race, and a cycling climb from Séez is organised every Friday.
