Race briefing
100K course102 km · 5943 m gain · 37% uphill
- Steep climb (10%+)
- Climb (3-10%)
- Flat
- Descent
- Steep descent (12%+)
The published GPX measures 102 km with 5943 m of climbing, 58 m per km. The course sits between 600 m and 2165 m of altitude. 62% of the gain sits in the first half.
- 0-11 km: 1575 m up / 84 m down; the stretch climbs.
- 11-29 km: 648 m up / 2092 m down; the stretch descends.
- 29-36 km: 1299 m up / 64 m down; the stretch climbs.
- 36-51 km: 157 m up / 1453 m down; the stretch descends.
- 51-102 km: 2264 m up / 2258 m down; the stretch keeps rolling.
The race climbs from the gun: 642 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 11: 1491 m over 11 km at 13% average, its steepest roughly 250 m section averaging 27%. It tops out at 2145 m. Heaviest kilometres: km 4 191 m, km 11 190 m, km 9 163 m, km 1 148 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 steepest wall stands between km 29 and km 36: 1235 m over 7.5 km at 17% average, its steepest roughly 250 m section averaging 28%. It tops out at 1936 m. Heaviest kilometres: km 31 255 m, km 32 233 m, km 33 216 m, km 35 184 m. By the time you start it, about 37% 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 12 and loses 1442 m by km 29 at 8% average, its steepest roughly 250 m section averaging 29%. 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 36 averages 20% 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 308 m. If anything is left in your legs, spend it here.
- The organiser lists 100 km; the published GPX measures 102 km. The organiser lists 5100 m of climbing; the published GPX measures 5943 m. The technical course notes use the published GPX measurement.
- This course reaches 2165 m. A separate forecast for the high-point coordinate gives 11°C to 20°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.
- Start 05:00, sunrise 06:10: the first 1 hour 10 minutes are run in the dark. The headtorch goes on your head at the start, not in your pack.
- Sunset is 20:18, 15 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 58 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.
- 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.
- 19% of the course is steep descent. Increase your cadence instead of braking, or your quads go early.
- The high point is 2165 m. Coming from sea level, your heart rate and breathing shift at the same pace, so leave yourself room in the first hour.
- The altitude is not a single summit: about 14 km of the course sits above 1800 m. The longest unbroken stretch up high is 10 km and the high zone spans roughly km 9 to km 19.
- Point to point: the finish sits 5.2 km from the start as the crow flies. Sort the shuttle and your drop bag before race day.
- At km 87.3 you pass right by the finish area with 14.4 km still to go; the noise there breaks more races than the climbs do.

Heaviest kilometres: km 4 191 m, km 11 191 m, km 9 163 m, km 1 148 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 steepest wall stands between km 28 and km 35: 1218 m over 7.3 km at 17% average, its steepest roughly 250 m section averaging 30%. It tops out at 1919 m. Heaviest kilometres: km 31 249 m, km 30 223 m, km 32 222 m, km 34 202 m. 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 12 and loses 1439 m by km 28 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 35 averages 20% 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 453 m first and then climb 95 m. Empty your legs on the descent and that final rise takes the payment.
