The race climbs from the gun: 324 m over the first 5 km. Do not chase the crowd, the two minutes you win here get taken back with interest.

The longest drag runs from km 0 to km 13: net 732 m over 13 km at 6% average, its steepest roughly 250 m section averaging 26%, 924 m of climbing in total with 192 m given back. It tops out at 2231 m. Heaviest kilometres: km 2 161 m, km 10 132 m, km 5 122 m, km 12 105 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.

The climb between km 21 and km 27: 990 m over 5.9 km at 17% average, its steepest roughly 250 m section averaging 42% on the GPX trace. It tops out at 2327 m. Kilometre by kilometre: km 22 24 m, km 23 49 m, km 24 159 m, km 25 214 m, km 26 333 m, km 27 225 m. Running is not on the menu at this grade; settle into a hike from the bottom and load the poles, short steps.

The climb between km 45 and km 52: 1161 m over 7 km at 17% average, its steepest roughly 250 m section averaging 36% on the GPX trace. It tops out at 2346 m. Heaviest kilometres: km 50 284 m, km 52 195 m, km 47 177 m, km 49 146 m. This is a hiking section, not a running section. Set the rhythm as a hike and move up without burning matches.

The backbone of the course runs from km 79 to km 91: 1709 m over 12 km at 14% average, its steepest roughly 250 m section averaging 45% on the GPX trace. It tops out at 2780 m. Heaviest kilometres: km 91 250 m, km 88 226 m, km 89 218 m, km 87 215 m. By the time you start it, about 68% of the day's climbing is behind you. Running is off the table only in the steepest roughly 250 m core; hike that part with short steps and run again once the grade eases.

The longest descent starts at km 91 and loses 1281 m by km 111 at 6% average, its steepest roughly 250 m section averaging 33% on the GPX trace. Its length can load the quads, so begin under control and build rhythm only when the ground and visibility allow it. The drop at km 52 averages 37% on the GPX trace over its steepest roughly 250 m section; shorten the stride, stay balanced and set speed to the ground instead of braking continuously.

The last 6 km drop 120 m. If anything is left in your legs, spend it here.

You reach the climb after Leukerbad with about 893 m of descent already in your quads; treat its first half as recovery effort.

You reach the climb after Kandersteg with about 1178 m of descent already in your quads; treat its first half as recovery effort.

A steep pitch starts within about 1.3 km of Kandersteg; keep the stop short and do not enter it on cooled-down legs.

A steep pitch starts within about 1.1 km of Chuenisbärgli; keep the stop short and do not enter it on cooled-down legs.

You reach the climb after Lenk with about 751 m of descent already in your quads; treat its first half as recovery effort.

A steep pitch starts within about 0.7 km of Lenk; keep the stop short and do not enter it on cooled-down legs.

A steep pitch starts within about 1.4 km of Barrage de Tseuzier; keep the stop short and do not enter it on cooled-down legs.

  • This course reaches 2790 m. A separate forecast for the high-point coordinate gives -2°C to 3°C, wind up to 7 km/h (calm). It is a daily forecast for that coordinate, so arrival time can still change what you encounter.
  • Poles are strongly recommended for this profile. The course averages 58 m of gain per km and the longest climb averaging over 5% runs 13 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
  • 20% 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 2790 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 45 km of the course sits above 1800 m, 5.3 km above 2400 m. The longest unbroken stretch up high is 13 km and the high zone spans roughly km 86 to km 99. About 47% of the total climbing happens in that thin air, so recalibrate your effort to the altitude, not the gradient alone.

Course-profile notes are generated from GPX grade data; terrain, rules, aid stations and weather are added only when separately sourced.

  • Cut-off: 14h 45m after the start.

Lenkkm 78

  • Collect food and fluids and leave within 60-90 seconds.
  • Crew access is allowed here.
  • A heavy leg is next: 8.4 km with 558 m of climbing.
  • Cut-off: 20h after the start.

Iffigenalpkm 86

  • Drinks only; arrive carrying your own food.

  • Cut-off: 22h 30m after the start.

Barrage de Tseuzierkm 103

  • Collect food and fluids and leave within 60-90 seconds.
  • Crew access is allowed here.
  • A heavy leg is next: 11 km with 277 m of climbing.
  • Cut-off: 28h 15m after the start.
  • The longest stretch between official aid stations runs from Gemmipass (km 28) to Kandersteg (km 44): 16 km. Top up at Gemmipass and size what you carry to the expected duration and your own drinking rate.
  • Drinks only, no food, at Varneralp (km 13) and Gemmipass (km 28) and 3 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.
  • Bunderchrinde (km 53) is a timing point only, with nothing on the table. Load up as you leave Ueschine.
  • Hot food is served at Adelboden (km 60). 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 Leukerbad (km 23) and Kandersteg (km 44) and 3 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 Adelboden (km 60). 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 Crans-Montana (km 0), Leukerbad (km 23), Kandersteg (km 44), Adelboden (km 60), Lenk (km 78), Col du Rawil (km 95), Barrage de Tseuzier (km 103), and Crans-Montana (km 114). 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 Barrage de Tseuzier (km 103), leaving 10 km to the finish. After that you are on what you carry.
  • The heaviest leg runs from Leukerbad (km 23) to Gemmipass (km 28): 5 km with 987 m of climbing. Treat it as the slowest part of your day and get your food out before it.
  • Medical support is available at Crans-Montana (km 0), Leukerbad (km 23), Gemmipass (km 28), Kandersteg (km 44), Bunderchrinde (km 53), Adelboden (km 60), Lenk (km 78), Iffigenalp (km 86), Cabane Wildstrubel (km 92), Col du Rawil (km 95), Barrage de Tseuzier (km 103), and Crans-Montana (km 114). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
  • About 2 km after Leukerbad (km 23), a roughly 250 m section averaging 42% begins. Choose food you know you digest easily and fill the bottles, then enter the climb at a controlled effort.
  • Relative to distance and climbing, the tightest official time budget runs from Start to Leukerbad (km 23): the official time budget is 4h 45m for 23 km and 985 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

The race climbs from the gun: 234 m over the first 5 km. Do not chase the crowd, the two minutes you win here get taken back with interest.

The climb between km 2 and km 10: 1150 m over 7.9 km at 14% average, its steepest roughly 250 m section averaging 37% on the GPX trace. It tops out at 2342 m. Heaviest kilometres: km 9 232 m, km 8 184 m, km 10 178 m, km 6 153 m. Running is off the table only in the steepest roughly 250 m core; hike that part with short steps and run again once the grade eases.

The backbone of the course runs from km 37 to km 49: 1701 m over 12 km at 14% average, its steepest roughly 250 m section averaging 48% on the GPX trace. It tops out at 2772 m. Heaviest kilometres: km 45 254 m, km 49 240 m, km 46 215 m, km 48 202 m. The hard core of this climb is hiking ground; keep the rest at a steady effort and do not fight the wall when it arrives.

The longest descent starts at km 49 and loses 1272 m by km 70 at 6% average, its steepest roughly 250 m section averaging 31% on the GPX trace. Its length can load the quads, so begin under control and build rhythm only when the ground and visibility allow it. The drop at km 10 averages 36% on the GPX trace over its steepest roughly 250 m section; shorten the stride, stay balanced and set speed to the ground instead of braking continuously.

The last 6 km drop 119 m. If anything is left in your legs, spend it here.

A steep pitch starts within about 1.6 km of Chuenisbärgli; keep the stop short and do not enter it on cooled-down legs.

You reach the climb after Lenk with about 837 m of descent already in your quads; treat its first half as recovery effort.

A steep pitch starts within about 1.2 km of Lenk; keep the stop short and do not enter it on cooled-down legs.

A steep pitch starts within about 1.9 km of Barrage de Tseuzier; keep the stop short and do not enter it on cooled-down legs.

  • The organiser lists 72 km; the published GPX measures 70.5 km. The technical course notes use the published GPX measurement.
  • This course reaches 2790 m. A separate forecast for the high-point coordinate gives -2°C to 3°C, wind up to 7 km/h (calm). It is a daily forecast for that coordinate, so arrival time can still change what you encounter.
  • Sunset is 19:51, 12 hours 51 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 63 m of gain per km and the longest climb averaging over 5% runs 12 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
  • 21% 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 2790 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 24 km of the course sits above 1800 m, 5.3 km above 2400 m. The longest unbroken stretch up high is 13 km and the high zone spans roughly km 45 to km 58. About 44% 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 25.1 km from the start as the crow flies. Sort the shuttle and your drop bag before race day.

  • Drinks only, no food, at Sillerebüel (km 27) and Iffigenalp (km 44). 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.
  • Ueschine - Point d'eau (only water) (km 8) is a timing point only, with nothing on the table.
  • Food is available at Adelboden (km 18) and Lenk (km 36) and 2 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.
  • Crew support is permitted only at Kandersteg (km 0), Adelboden (km 18), Lenk (km 36), Barrage de Tseuzier (km 61), and Crans-Montana (km 72).

If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
  • About 0.5 km after Ueschine - Point d'eau (only water) (km 8), a roughly 250 m section averaging 37% begins. Nothing is served at this point, so arrive already stocked from the previous aid station, then enter the climb at a controlled effort.
  • Relative to distance and climbing, the tightest official time budget runs from Lenk (km 36) to Iffigenalp (km 44): the official time budget is 2h for 8 km and 703 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

The published GPX measures 54 km with 3136 m of climbing, 58 m per km. The course sits between 1065 m and 2789 m of altitude. 50% of the gain sits in the first half.

  • 0-4.7 km · Start → Chuenisbärgli: 435 m up / 59 m down; the stretch climbs.

The race climbs from the gun: 370 m over the first 4.3 km. Do not chase the crowd, the two minutes you win here get taken back with interest.

The climb between km 1 and km 5: 425 m over 3.9 km at 11% average, its steepest roughly 250 m section averaging 14%. Kilometre by kilometre: km 2 103 m, km 3 100 m, km 4 129 m, km 5 83 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.

The climb between km 7 and km 12: 539 m over 5.7 km at 9% average, its steepest roughly 250 m section averaging 27%. It tops out at 2026 m. Kilometre by kilometre: km 8 132 m, km 9 125 m, km 10 196 m, km 11 58 m, km 12 45 m. Trying to run this costs far more than it saves. Shorten the stride, lean on the poles, keep moving.

The backbone of the course runs from km 20 to km 33: 1701 m over 12 km at 14% average, its steepest roughly 250 m section averaging 50% on the GPX trace. It tops out at 2766 m. Heaviest kilometres: km 30 231 m, km 28 225 m, km 29 211 m, km 33 207 m. Running is off the table only in the steepest roughly 250 m core; hike that part with short steps and run again once the grade eases.

The longest descent starts at km 33 and loses 1233 m by km 46 at 9% average, its steepest roughly 250 m section averaging 31% on the GPX trace. Its length can load the quads, so begin under control and build rhythm only when the ground and visibility allow it. The drop at km 12 averages 32% on the GPX trace over its steepest roughly 250 m section; shorten the stride, stay balanced and set speed to the ground instead of braking continuously.

The last 6 km drop 125 m. If anything is left in your legs, spend it here.

You reach the climb after Lenk with about 878 m of descent already in your quads; treat its first half as recovery effort.

A steep pitch starts within about 1.3 km of Lenk; keep the stop short and do not enter it on cooled-down legs.

A steep pitch starts within about 2 km of Barrage de Tseuzier; keep the stop short and do not enter it on cooled-down legs.

  • The organiser lists 55 km; the published GPX measures 53.7 km. The technical course notes use the published GPX measurement.
  • This course reaches 2789 m. A separate forecast for the high-point coordinate gives -2°C to 3°C, wind up to 7 km/h (calm). It is a daily forecast for that coordinate, so arrival time can still change what you encounter.
  • Sunset is 19:51, 12 hours 1 minute 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 58 m of gain per km and the longest climb averaging over 5% runs 12 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
  • 18% 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 2789 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 19 km of the course sits above 1800 m, 5.2 km above 2400 m. The longest unbroken stretch up high is 13 km and the high zone spans roughly km 28 to km 41. About 43% 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 21 km from the start as the crow flies. Sort the shuttle and your drop bag before race day.

Course-profile notes are generated from GPX grade data; terrain, rules, aid stations and weather are added only when separately sourced.

  • Crew access is allowed here.
  • A heavy leg is next: 8.3 km with 547 m of climbing.
  • Cut-off: 5h 10m after the start.

Iffigenalpkm 27

  • Drinks only; arrive carrying your own food.
  • The heaviest leg is next: 5.8 km with 1230 m of climbing.
  • A 28% pitch starts about 0.5 km after the station; do not enter it cooled down.
  • Cut-off: 7h 10m after the start.

Barrage de Tseuzierkm 44

  • Collect food and fluids and leave within 60-90 seconds.
  • A heavy leg is next: 11 km with 310 m of climbing.
  • The longest unsupported stretch starts here: 11 km. Leave with full capacity.
  • Cut-off: 12h 25m after the start.
  • The longest stretch between official aid stations runs from Barrage de Tseuzier (km 44) to Crans-Montana (km 55): 11 km, with 310 m of climbing in between. Top up at Barrage de Tseuzier and size what you carry to the expected duration and your own drinking rate.
  • Drinks only, no food, at Sillerebüel (km 10) and Iffigenalp (km 27). 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.
  • Chuenisbärgli (km 5) is a timing point only, with nothing on the table.
  • Food is available at Lenk (km 19) and Cabane Wildstrubel (km 33) and 1 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.
  • Crew support is permitted only at Adelboden (km 0), Lenk (km 19), and Crans-Montana (km 55). 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 heaviest leg runs from Iffigenalp (km 27) to Cabane Wildstrubel (km 33): 6 km with 1230 m of climbing. Treat it as the slowest part of your day and get your food out before it.
  • Medical support is available at Adelboden (km 0), Lenk (km 19), Iffigenalp (km 27), Cabane Wildstrubel (km 33), Barrage de Tseuzier (km 44), and Crans-Montana (km 55). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
  • About 0.5 km after Iffigenalp (km 27), a roughly 250 m section averaging 28% begins. Only drinks are served here, so fill the bottles and carry your own food in, then enter the climb at a controlled effort.
  • Relative to distance and climbing, the tightest official time budget runs from Lenk (km 19) to Iffigenalp (km 27): the official time budget is 2h for 8 km and 565 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.
