What the weather is usually like here

  • Over the last 5 years this week typically ran 13°C to 23°C here, with a high of 31°C and a low of 9°C.
  • 71% of those days saw rain. A real forecast lands about two weeks out and will appear here then.
  • Typical daily maximum wind was 7 km/h (calm), with 12 km/h the highest value in the sample.
  • It has been hot here before: if race week trends warm, scale your fluid plan up.
  • Sunrise 05:48, sunset 21:18.

The race is more than two weeks out, so these are averages of recent years for the same week, not a forecast. A real forecast appears here closer to the day.

The published GPX measures 261 km with 18543 m of climbing, 71 m per km. The course sits between 620 m and 2780 m of altitude. 58% of the gain sits in the first half.

  • 0-24 km · Start → Stechelberg: 1753 m up / 1905 m down; the stretch descends.
  • 24-60 km · Stechelberg → Kandersteg: 3714 m up / 3408 m down; the stretch climbs.
  • 60-95 km · Kandersteg → Jeizinen: 2357 m up / 2517 m down; the stretch descends.
  • 95-119 km · Jeizinen → Finnen: 1824 m up / 1599 m down; the stretch climbs.
  • 119-134 km · Finnen → Belalp: 1198 m up / 769 m down; the stretch climbs.
  • 134-179 km · Belalp → Bellwald: 3243 m up / 3286 m down; the stretch keeps rolling.
  • 179-207 km · Bellwald → Oberwald: 2066 m up / 1648 m down; the stretch climbs.
  • 207-234 km · Oberwald → Guttannen: 591 m up / 1931 m down; the stretch descends.
  • 234-261 km · Guttannen → Finish: 1797 m up / 1484 m down; the stretch climbs.

The first 5 km drop 92 m and then climb 656 m back. Fresh legs make the descent feel free, but the climb comes straight after.

The backbone of the course runs from km 22 to km 35: 1742 m over 13 km at 14% average, its steepest roughly 250 m section averaging 41% on the GPX trace. It tops out at 2588 m. Heaviest kilometres: km 26 252 m, km 35 229 m, km 31 219 m, km 30 204 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 drag runs from km 59 to km 74: net 1512 m over 15 km at 10% average, its steepest roughly 250 m section averaging 33% on the GPX trace, 1727 m of climbing in total with 215 m given back. It tops out at 2691 m. Heaviest kilometres: km 72 272 m, km 70 264 m, km 74 208 m, km 69 192 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 209 and loses 1582 m by km 237 at 6% average, its steepest roughly 250 m section averaging 22%. 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 45 averages 38% 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 557 m. If anything is left in your legs, spend it here.

You reach the climb after Stechelberg with about 1905 m of descent already in your quads; treat its first half as recovery effort.

You reach the climb after Jeizinen with about 2517 m of descent already in your quads; treat its first half as recovery effort.

You reach the climb after Finnen with about 1599 m of descent already in your quads; treat its first half as recovery effort.

A steep pitch starts within about 1.8 km of Finnen; keep the stop short and do not enter it on cooled-down legs.

The leg from Belalp to Bellwald is long and unsupported: 45 km and 3243 m of climbing with no aid in between, so leave Belalp with full capacity.

You reach the climb after Bellwald with about 3286 m of descent already in your quads; treat its first half as recovery effort.

You reach the climb after Guttannen with about 1931 m of descent already in your quads; treat its first half as recovery effort.

  • This course reaches 2780 m. At the high-point coordinate, the same week historically ran 1°C to 10°C. Typical daily maximum wind was 9 km/h, reaching 12 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 21:18, 13 hours 18 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 71 m of gain per km and the longest climb averaging over 5% runs 15 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
  • 22% 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 2780 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 87 km of the course sits above 1800 m, 7.9 km above 2400 m. The longest unbroken stretch up high is 21 km and the high zone spans roughly km 69 to km 90.

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

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 Guttannen (km 234), leaving 27 km to the finish. After that you are on what you carry.
  • The heaviest leg runs from Stechelberg (km 24) to Kandersteg (km 60): 36 km with 3715 m of climbing. Treat it as the slowest part of your day and get your food out before it.

  • 96-99 km · Pfingstegg → Finish: 73 m up / 172 m down; gently rolling.

The race climbs from the gun: 347 m over the first 5 km. Do not chase the crowd, the two minutes you win here get taken back with interest.

The backbone of the course runs from km 0 to km 14: 1094 m over 14 km at 8% average, its steepest roughly 250 m section averaging 36% on the GPX trace. It tops out at 2128 m. Heaviest kilometres: km 6 208 m, km 8 196 m, km 5 147 m, km 9 133 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.

The climb between km 18 and km 28: net 837 m over 10 km at 8% average, its steepest roughly 250 m section averaging 24%, 957 m of climbing in total with 120 m given back. It tops out at 2401 m. Heaviest kilometres: km 21 181 m, km 23 171 m, km 20 139 m, km 24 102 m. Trying to run this costs far more than it saves. Shorten the stride, lean on the poles, keep moving.

The climb between km 63 and km 73: 1035 m over 9.9 km at 10% average, its steepest roughly 250 m section averaging 31% on the GPX trace. It tops out at 2314 m. Heaviest kilometres: km 66 252 m, km 65 244 m, km 67 201 m, km 64 173 m. By the time you start it, about 62% 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 34 and loses 1780 m by km 54 at 9% average, its steepest roughly 250 m section averaging 32% 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 81 averages 26% 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 roll: 375 m up and 466 m down. Do not start the finishing effort early, there is another climb in there.

You reach the climb after Bort with about 636 m of descent already in your quads; treat its first half as recovery effort.

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

A steep pitch starts within about 1 km of Schwand; keep the stop short and do not enter it on cooled-down legs.

You reach the climb after Burglauenen with about 766 m of descent already in your quads; treat its first half as recovery effort.

The leg from Männlichen to Kleine Scheidegg is long and unsupported: 10 km and 423 m of climbing with no aid in between, so leave Männlichen with full capacity.

You reach the climb after Kleine Scheidegg with about 620 m of descent already in your quads; treat its first half as recovery effort.

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

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

  • The organiser lists 101 km; the published GPX measures 99.1 km. The organiser lists 6700 m of climbing; the published GPX measures 6348 m. The technical course notes use the published GPX measurement.
  • This course reaches 2679 m. At the high-point coordinate, the same week historically ran 3°C to 12°C. Typical daily maximum wind was 8 km/h, reaching 13 km/h in the sample. This is climate history, not the race-day forecast; keep the shell accessible if race week looks similar.
  • Start 04:00, sunrise 05:49: the first 1 hour 49 minutes are run in the dark. The headtorch goes on your head at the start, not in your pack.
  • Sunset is 21:19, 17 hours 19 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 64 m of gain per km and the longest climb averaging over 5% runs 14 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
  • 27% 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 2679 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 55 km of the course sits above 1800 m, 4 km above 2400 m. The longest unbroken stretch up high is 26 km and the high zone spans roughly km 20 to km 46. About 52% of the total climbing happens in that thin air, so recalibrate your effort to the altitude, not the gradient alone.

Kilometre by kilometre: km 23 77 m, km 24 224 m, km 25 224 m, km 26 111 m. By the time you start it, about 59% of the day's climbing is behind you. Running is not on the menu at this grade; settle into a hike from the bottom and load the poles, short steps.

The longest descent starts at km 26 and loses 1758 m by km 45 at 9% average, its steepest roughly 250 m section averaging 27%. 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 19 averages 22% 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 climb 68 m to the line. Know it going in and save something for it.

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

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

A steep pitch starts within about 0.8 km of Burglauenen; keep the stop short and do not enter it on cooled-down legs.

  • The organiser lists 51 km; the published GPX measures 52.1 km. The organiser lists 3100 m of climbing; the published GPX measures 2832 m. The technical course notes use the published GPX measurement.
  • This course reaches 2679 m. At the high-point coordinate, the same week historically ran 3°C to 12°C. Typical daily maximum wind was 8 km/h, reaching 13 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 21:19, 14 hours 4 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 54 m of gain per km and the longest climb averaging over 5% runs 19 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
  • The climbing is stacked into the first half. Start easy; even with less climbing later, the descents and accumulated fatigue still have to be managed.
  • 16% 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 2679 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 30 km of the course sits above 1800 m, 4 km above 2400 m. The longest unbroken stretch up high is 30 km and the high zone spans roughly km 8 to km 37. About 58% 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.

  • The last aid station is Burglauenen (km 46), leaving 5 km to the finish. After that you are on what you carry.
  • Another heavy leg runs from Feld (km 21) to Faulhorn (km 26): 5 km with 676 m of climbing. Treat it as the slowest part of your day and get your food out before it.
  • Medical support is available at Start (km 0), Gr. Scheidegg (km 9), First (km 15), Feld (km 21), Faulhorn (km 26), Schwand (km 39), Burglauenen (km 46), and Finish (km 53). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
  • About 2 km after Feld (km 21), a roughly 250 m section averaging 23% begins. Choose food you know you digest easily and fill the bottles, then enter the climb at a controlled effort.

The drop at km 33 averages 22% over its steepest roughly 250 m section; shorten the stride, stay balanced and set speed to the ground instead of braking continuously.

The last 4.3 km drop 219 m first and then climb 157 m. Empty your legs on the descent and that final rise takes the payment.
