The event

The Trail Verbier St-Bernard by UTMB is a mountain trail running event and part of the UTMB World Series.

For the next edition, taking place from 9 to 11 July 2027, the organisation is introducing several changes:** three days of racing and two 50K race formats.**

The current Verbier Marathon will be renamed the Verbier Marathon X-Treme – 43 km / 3,000 m D+, retaining its iconic passage over the summit of Mont Rogneux. Technical and alpine, this course is designed for runners who already have experience on this type of terrain. To reduce congestion in the more technical sections, the number of participants will now be limited to 800 runners.

A second race, the Verbier Marathon – 47 km / 2,900 m D+, will bypass Mont Rogneux from the Col de Mille via Cabane Brunet. Although slightly longer in distance, this new course is less technically demanding and therefore a little more runnable. The number of participants will be limited to 1,100 runners.

Both races will start simultaneously from Moay before splitting at Cabane de Mille. They will take place on Friday, 9 July 2027, starting at 7:15 am.

The other races will remain unchanged: the X-Alpine – 140 km / 9,300 m D+, starting from Verbier on Friday, 9 July at 10:00 pm; the X-Traversée – 77 km / 5,300 m D+, starting from La Fouly on Saturday, 10 July from 9:00 am; and the Verbier X-Plore – 28 km / 1,700 m D+, starting from Verbier on Sunday, 11 July from 7:30 am.

Two challenges are also offered for young participants in the streets of Verbier: a running race for children aged 4 to 14 and an orienteering race for young people aged 12 to 17.

Every race finishes in Verbier. An authentic alpine village in the heart of the Swiss Alps.

Before becoming a touristic destination famous for its numerous outdoor activities, Verbier was once a remote alpine pasture where only a few farmers lived all year round. Even though it's now much bigger, its previous charm has been preserved and the old Verbier village hasn't changed much through time.

Verbier has got everything you need (hotels, appartments, restaurants, sport shops...) to welcome you before and after your race and can easily be reached by public transports.

The association "Les Trailers Verbier St-Bernard" organise TVSB since its begining. Founded in 2009 by a local team wishing to develop trail running in Switzerland and in the area, it's with a lot of passion and grit that it persues its goal and works all year long to organise a high-standard event.

Anybody whishing to join the association is welcome. You can become a member as a runner, a volunteer or just to support us.
