Trail Verbier St Bernard by UTMB, live.

Over the Grand St Bernard and back to Verbier

Three days of racing in the Valais Alps, 9 to 11 July 2027, all finishing in Verbier. The long courses cross into Italy at the Grand St Bernard pass and come home past the Grand Combin.

The organiser publishes five adult trail races and two for young runners. X-Alpine is 140 km with 9,300 m of ascent and a 42-hour limit, starting from Verbier at 22:00 on Friday. X-Traversée starts in La Fouly on Saturday: 77 km, 5,300 m. The Verbier Marathon (47 km, 2,900 m) and the more technical Verbier Marathon X-Treme (43 km, 3,000 m) both start on Friday morning at Moay, above Bruson, reached by gondola from Le Châble. Sunday has X-Plore (28 km, 1,700 m), the X-Orient orienteering race for teenagers and the Trail Découverte for children.

The landmarks are named on the race pages: Champex and its lake, the Orny hut by the first glacier, the Fenêtre lakes, the hospice on the Grand St Bernard, the Panossière glacier and its suspension bridge, and Mont Rogneux at 3,084 m on the X-Treme. Almost every course ends the same way, on a wall of roughly 1,200 m above Verbier and the descent into the resort.

Between those names lie long stretches of high ground, glacier valleys and a night out for the X-Alpine field. A runner can share a link to their own Livebib broadcast; family and friends open it in a browser, with no account and no app, and see the position on the course line, distance covered and a finish estimate that updates as the race goes. When the phone loses signal in a valley, the position is carried forward along the course and marked as estimated instead of freezing. The runner decides who gets the link.
