Verbier Ultra: Course, Elevation & Route Profile

The Traversée de Bagnes is not a one-day ultra but a crossing in three stages: around 102 kilometres and some 8,000 metres of climbing straight through the Val de Bagnes, with two nights in mountain huts. What you prepare for is therefore not one long effort but the ability to produce it three days in a row.

Course & Elevation

The first stage leaves the base camp at Camping de Bonatchiesse at 10:00 a.m. on the Friday and goes steep immediately: from kilometre 1.7 there are a good 1,000 metres of climbing packed into just over four, averaging 24 percent, before the route reaches the Cabane du Mont-Fort via the Cabane de Louvie. Nineteen kilometres, but a full mountain day.

The second stage is the longest. From Mont-Fort it runs across the heights above Verbier to the Cabane de Mille and on to the Cabane Brunet; at its core is a climb of some nine kilometres and a good 1,600 metres, the largest single ascent of the whole crossing. The third stage closes the circle from the Cabane Brunet via the Cabane FXB Panossière and Chanrion, then along the Lac de Mauvoisin back to Bonatchiesse.

Across all three days, more than two thirds of the route sits in steep up or steep down terrain and barely five percent is flat: this race has almost no stretches where a running rhythm can settle. It is put on by the non-profit association Les Coureurs UltraSolidaires, and it is run semi-autonomously with a GPS watch, headtorch, a litre of water capacity and full weather protection. You sleep in the huts where the stages end.

Pacing Strategy

A stage race is paced around recovery, not around a fast day. The opening climb from kilometre 1.7 at 24 percent average is exactly where an over-ambitious Friday ruins your Sunday: take it at a pace you could still repeat on day three, and use the short stage as a way into the crossing.

The race is decided on the long climb of the second stage: nine kilometres, a good 1,600 metres, with the previous day in your legs and a night above 2,400 m behind you. Climb it evenly and still manage to eat at the Cabane de Mille, and you reach the Cabane Brunet in a state from which the third stage can be raced.

The real trap is the descending. More than a third of the route drops steeply, and stages two and three each bring over 3,200 metres of descent, the muscular bill for which arrives the following morning. Brake deliberately and under control, keep the cut-offs in view (4 p.m., 6 p.m. and 5:30 p.m.), and treat eating and drinking in the huts as part of the race rather than as the evening off.

Training plan for Verbier Ultra: 12-week build

Expect five to ten hours per stage and, across three days, a total load of roughly twenty to thirty hours. The character is aerobic throughout but anything but even: long blocks of steep hiking, equally long technical descents, and hardly any flat. Build running volume alone and you have prepared the wrong demand.

The decisive training content is consecutive hard days. Back-to-back weekend sessions (a long mountain outing on Saturday and another on Sunday, deliberately on tired legs) rehearse the structure of the race directly. A single very long run each week does not.

The decisive sections are the 24-percent opening on day one and the 1,600-metre climb on day two. Both call for economical climbing over hours rather than uphill running, and both arrive when the body is already loaded. Train steep hiking specifically, and plan long sessions whose biggest climb comes late.

For conditions, the high-mountain character is what counts. The route runs hut to hut over the passes of the Val de Bagnes, mid-September can bring snow up there, and you sleep in mountain huts rather than a hotel. Train at altitude, test the full mandatory kit including headtorch and weather protection on long days, and practise eating and sleeping in simple conditions. Semi-autonomy also means that recovery between stages is part of the preparation.

Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
