Race briefing
57K course57 km · 1144 m gain · 28% uphill
- Steep climb (10%+)
- Climb (3-10%)
- Flat
- Descent
The published GPX measures 57 km with 1144 m of climbing, 20 m per km. The course sits between 40 m and 505 m of altitude. 63% of the gain sits in the first half.
- 0-17 km: 591 m up / 126 m down; the stretch climbs.
- 17-23 km: 13 m up / 217 m down; the stretch descends.
- 23-31 km: 130 m up / 207 m down; gently rolling.
- 31-36 km: 206 m up / 4 m down; the stretch climbs.
- 36-51 km: 181 m up / 315 m down; the stretch descends.
- 51-57 km: 26 m up / 277 m down; the stretch descends.
The race climbs from the gun: 112 m over the first 4.6 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 17: net 465 m over 17 km at 3% average, its steepest roughly 250 m section averaging 17%, 591 m of climbing in total with 126 m given back. Heaviest kilometres: km 10 103 m, km 9 77 m, km 5 63 m, km 12 44 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.
The climb between km 31 and km 36: 202 m over 5.3 km at 4% average, its steepest roughly 250 m section averaging 10%. Kilometre by kilometre: km 32 37 m, km 33 81 m, km 35 19 m, km 36 44 m. Runnable, but this is where a race gets thrown away one gear too hard.
The longest descent starts at km 51 and loses 251 m by km 57 at 4% average, its steepest roughly 250 m section averaging 8%. 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 44 averages 11% 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 192 m. If anything is left in your legs, spend it here.
- This course reaches 505 m. At the high-point coordinate, the same week historically ran 6°C to 14°C. Typical daily maximum wind was 14 km/h, reaching 39 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 17:37, 8 hours 37 minutes after the gun. If your target time is longer than that, carry a headtorch whether or not the rules demand one.
- Organiser rule: Runners with poles who leave their poles behind before finishing the race will receive an additional 1-hour time penalty.
- Poles are optional: 20 m of gain per km. Bring them to protect your legs, not to gain speed.
- 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.
- At km 55.4 you pass right by the finish area with 2.1 km still to go; the noise there breaks more races than the climbs do.
Course-profile notes are generated from GPX grade data; terrain, rules, aid stations and weather are added only when separately sourced.

- Steep climb (10%+)

The first 1.6 km are close to flat, good for settling in. Do not set your pace here, the real course starts after.
The backbone of the course runs from km 0 to km 8: net 275 m over 7.9 km at 3% average, its steepest roughly 250 m section averaging 14%, 313 m of climbing in total with 38 m given back. Heaviest kilometres: km 8 104 m, km 4 65 m, km 5 33 m, km 6 30 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.
The longest descent starts at km 14 and loses 241 m by km 20 at 4% average, its steepest roughly 250 m section averaging 8%. Its length can load the quads, so begin under control and build rhythm only when the ground and visibility allow it.
The last 2.5 km drop 104 m. If anything is left in your legs, spend it here.
- Sunset is 17:37, 8 hours 37 minutes after the gun. If your target time is longer than that, carry a headtorch whether or not the rules demand one.

The longest descent starts at km 8 and loses 157 m by km 14 at 3% average, its steepest roughly 250 m section averaging 11%. Its length can load the quads, so begin under control and build rhythm only when the ground and visibility allow it.
The last 2 km are close to flat. Plan your finishing pace around that, there is nothing left to save.
- Sunset is 17:37, 8 hours 7 minutes after the gun. If your target time is longer than that, carry a headtorch whether or not the rules demand one.
- Organiser rule: Runners with poles who leave their poles behind before finishing the race will receive an additional 1-hour time penalty.
- Poles are optional: 17 m of gain per km. Bring them to protect your legs, not to gain speed.
- Out and back: you turn at km 7 and return the same way. Note how easy the outward leg felt, you pay for it in reverse.
- Km 7.3 to 14 is the same ground you covered at km 6.8; note your pace on the first pass and use it as the yardstick on the second.
