Trail Verbier St Bernard by UTMBVerbier, Switzerland🇨🇭

• •The organiser lists 140 km; the published GPX measures 138 km. The technical course notes use the published GPX measurement.
• •This course reaches 2819 m. At the high-point coordinate, the same week historically ran 1°C to 9°C. Typical daily maximum wind was 6 km/h, reaching 9 km/h in the sample. This is climate history, not the race-day forecast; keep the shell accessible if race week looks similar.
• •Sunset is 21:23 and the finish cut-off is 14:30. A runner using the full time allowance spends the final 7 hours 49 minutes in darkness.
• •Get the headtorch out before sunset and keep spare batteries or a power bank dry and immediately accessible. A spare buried at the bottom of the pack is not an emergency spare.
• •Check reflective course markers regularly in the dark. If the markings disappear, stop moving forward, return to the last marker and confirm the route against the GPX or organiser app.
• •At cut-off pace you run into a second night. Plan the sleep question before race day: an hour gained on the first night costs two on the second.
• •Poles are strongly recommended for this profile. The course averages 67 m of gain per km and the longest climb averaging over 5% runs 23 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
• •26% of the course is steep descent. Increase your cadence instead of braking, or your quads go early.
• •Arrive early for the altitude. The course tops out at 2819 m, and coming up from sea level on race morning costs you more than any training block gains. Get to the area a few days ahead and let your body adjust.
• •The altitude is not a single summit: about 80 km of the course sits above 1800 m, 24 km above 2400 m. The longest unbroken stretch up high is 30 km and the high zone spans roughly km 90 to km 120. About 65% of the total climbing happens in that thin air, so recalibrate your effort to the altitude, not the gradient alone.

Aid stations

• •The longest stretch between official aid stations runs from Savoleyres (km 13) to Sembrancher (km 30): 17 km, with 190 m of climbing in between. Top up at Savoleyres and size what you carry to the expected duration and your own drinking rate.
• •Drinks only, no food, at Savoleyres (km 13) and Orny (km 46) and 1 more. Loosen the flask caps on approach; with no queue, refill and leave in 20-30 seconds. Carry the food you will need from the previous station.
• •Plan la Chaux (km 68) is a timing point only, with nothing on the table. Load up as you leave La Fouly.
• •Hot food is served at La Fouly (km 61) and Bourg St Pierre (km 89) and 1 more. If your stomach and race plan call for it, make this a deliberate 3-5 minute stop; do not sit down simply because hot food is available. Restart gently and let your stomach settle before lifting the effort.
• •Food is available at Sembrancher (km 30) and Champex (km 38) and 4 more. Decide what you need before reaching the table; without a planned special task, collect food and fluids and leave within 60-90 seconds. Finish eating on the next calm, suitable section.
• •Drop bag at Bourg St Pierre (km 89). Write down the equipment and food you expect to replace before the race so the decision is already made when you arrive.
• •Crew support is permitted only at Verbier (km 0), Champex (km 38), La Fouly (km 61), Col des Chevaux (km 77), Bourg St Pierre (km 89), Cabane Brunet (km 109), Lourtier (km 128), La Chaux (km 134), and Verbier (km 141). This is not the same as a drop bag: plan equipment and food hand-offs around these stations, then verify wristband, bag and transport rules with the organiser.
• •The last aid station is La Chaux (km 134), leaving 6 km to the finish. After that you are on what you carry.
• •The heaviest leg runs from Champex (km 38) to Orny (km 46): 9 km with 1414 m of climbing. Treat it as the slowest part of your day and get your food out before it.
• •Medical support is available at Verbier (km 0), Savoleyres (km 13), Sembrancher (km 30), Champex (km 38), Orny (km 46), La Fouly (km 61), Col Fenêtre (km 72), Gd St Bernard (km 75), Bourg St Pierre (km 89), Cabane de Mille (km 101), Cabane Brunet (km 109), Cabane Panossière (km 116), Lourtier (km 128), La Chaux (km 134), and Verbier (km 141). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
• •About 1 km after Lourtier (km 128), a roughly 250 m section averaging 34% begins. Choose food you know you digest easily and fill the bottles, then enter the climb at a controlled effort.
• •The overall cut-off is 40h 30m, including all checkpoint stops. Build the plan around the official leg budgets below, not a flat-course average pace.
• •Relative to distance and climbing, the tightest official time budget runs from Start to Sembrancher (km 30): the official time budget is 6h 5m for 30 km and 1422 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

Aid station details come from the list published by the organiser; confirm them at the official source before race day.

• •The organiser lists 77 km; the published GPX measures 75.8 km. The technical course notes use the published GPX measurement.

• •Sunset is 21:22, 12 hours 22 minutes after the gun. If your target time is longer than that, carry a headtorch whether or not the rules demand one.
• •Poles are strongly recommended for this profile. The course averages 69 m of gain per km and the longest climb averaging over 5% runs 11 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.

About 76% of the total climbing happens in that thin air, so recalibrate your effort to the altitude, not the gradient alone.
• •Point to point: the finish sits 20.8 km from the start as the crow flies. Sort the shuttle and your drop bag before race day.
