Course map and elevation profile
What the weather is usually like here
- Over the last 5 years this week typically ran 6°C to 13°C here, with a high of 20°C and a low of 2°C.
- 60% of those days saw rain. A real forecast lands about two weeks out and will appear here then.
- Typical daily maximum wind was 15 km/h (a light breeze), with 28 km/h the highest value in the sample.
- Sunrise 05:55, sunset 21:01.
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 first 5 km drop 156 m and then climb 130 m back. Fresh legs make the descent feel free, but the climb comes straight after.
The backbone of the course runs from km 23 to km 32: 750 m over 8.8 km at 9% average, its steepest roughly 250 m section averaging 19%. Heaviest kilometres: km 24 130 m, km 28 123 m, km 29 103 m, km 32 101 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.
The longest drag runs from km 110 to km 123: net 542 m over 14 km at 4% average, its steepest roughly 250 m section averaging 16%, 696 m of climbing in total with 154 m given back. Heaviest kilometres: km 117 137 m, km 113 123 m, km 114 97 m, km 112 90 m. By the time you start it, about 72% of the day's climbing is behind you. Trying to run this costs far more than it saves. Shorten the stride, lean on the poles, keep moving.
The late climb from km 133 to km 139: 485 m over 5.8 km at 8% average, its steepest roughly 250 m section averaging 18%. Kilometre by kilometre: km 134 44 m, km 135 143 m, km 136 31 m, km 137 68 m, km 138 95 m, km 139 102 m. By the time you start it, about 87% of the day's climbing is behind you. At this point in the day most runners walk this gradient. Settle into a hiking rhythm and let the metres come.
The longest descent starts at km 139 and loses 594 m by km 157 at 3% average, its steepest roughly 250 m section averaging 17%. 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 59 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 106 m. If anything is left in your legs, spend it here.
You reach the climb after Lapoutroie with about 861 m of descent already in your quads; treat its first half as recovery effort.
A steep pitch starts within about 0.4 km of Lapoutroie; keep the stop short and do not enter it on cooled-down legs.
The leg from Aubure to Ch. Oedenbourg is long and unsupported: 20 km and 712 m of climbing with no aid in between, so leave Aubure with full capacity.
- The organiser lists 5100 m of climbing; the published GPX measures 5702 m. The technical course notes use the published GPX measurement.
- Sunset is 21:01 and the finish cut-off is 09:15. A runner using the full time allowance spends the final 8 hours 54 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.
- Consider bringing poles. The course averages 36 m of gain per km and the longest climb averaging over 5% runs 8.8 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
- Point to point: the finish sits 46.5 km from the start as the crow flies. Sort the shuttle and your drop bag before race day.

- The longest stretch between official aid stations runs from Aubure (km 40) to Ch. Oedenbourg (km 60): 20 km, with 725 m of climbing in between. Top up at Aubure and size what you carry to the expected duration and your own drinking rate.
- Ch. Oedenbourg (km 60) is a timing point only, with nothing on the table. Load up as you leave Aubure.
- Hot food is served at Chatenois (km 68) and Barr (km 111). 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 Auberge du Lac Noir (km 9) and Lapoutroie (km 22) and 7 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 Chatenois (km 68). 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 Auberge du Lac Noir (km 9), Lapoutroie (km 22), Aubure (km 40), Ch.

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 Rosheim (km 151), leaving 7 km to the finish. After that you are on what you carry.
- The heaviest leg runs from Lapoutroie (km 22) to Aubure (km 40): 17 km with 910 m of climbing. Treat it as the slowest part of your day and get your food out before it.
- Medical support is available at Lac Blanc (km 0), Auberge du Lac Noir (km 9), Lapoutroie (km 22), Aubure (km 40), Ch. Haut-Koenigsbourg (km 60), Chatenois (km 68), Dambach-la-Ville (km 81), Andlau (km 98), Barr (km 111), Abbaye de Niedermunster (km 128), Klingenthal (km 135), Rosheim (km 151), and Obernai (km 159). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
- The climbing starts the moment you leave Andlau (km 98): the steepest roughly 250 m section averages 24%. Choose food you know you digest easily and fill the bottles, then begin the climb under control.
- The overall cut-off is 40h 15m, 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 Auberge du Lac Noir (km 9) to Lapoutroie (km 22): the official time budget is 2h 20m for 14 km and 339 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: 160 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 60 to km 74: net 542 m over 14 km at 4% average, its steepest roughly 250 m section averaging 17%, 703 m of climbing in total with 161 m given back. Heaviest kilometres: km 64 119 m, km 68 119 m, km 63 112 m, km 65 80 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.
The late climb from km 84 to km 90: 480 m over 5.8 km at 8% average, its steepest roughly 250 m section averaging 17%. Kilometre by kilometre: km 85 75 m, km 86 114 m, km 87 35 m, km 88 67 m, km 89 111 m, km 90 74 m. By the time you start it, about 82% of the day's climbing is behind you. At this point in the day most runners walk this gradient. Settle into a hiking rhythm and let the metres come.
The longest descent starts at km 90 and loses 592 m by km 108 at 3% average, its steepest roughly 250 m section averaging 17%. 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 79 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 climb 148 m and then drop 196 m. Walk the climb, take the descent back, and hold the sprint until the drop is done.
A steep pitch starts within about 0.3 km of Château de Kintzheim; keep the stop short and do not enter it on cooled-down legs.
The leg from Dambach-la-Ville to Andlau is long and unsupported: 17 km and 858 m of climbing with no aid in between, so leave Dambach-la-Ville with full capacity.
- The organiser lists 3900 m of climbing; the published GPX measures 4204 m. The technical course notes use the published GPX measurement.
- This course reaches 778 m. At the high-point coordinate, the same week historically ran 8°C to 16°C. Typical daily maximum wind was 15 km/h, reaching 24 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 21:01 and the finish cut-off is 07:45. A runner using the full time allowance spends the final 8 hours 52 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.
- Consider bringing poles. The course averages 39 m of gain per km and the longest climb averaging over 5% runs 5.8 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
- Point to point: the finish sits 25.5 km from the start as the crow flies. Sort the shuttle and your drop bag before race day.

- Another heavy leg runs from Orschwiller (km 0) to Ch. Oedenbourg (km 10): 10 km with 573 m of climbing. Treat it as the slowest part of your day and get your food out before it.
- Medical support is available at Orschwiller (km 0), Château du Haut-Koenigsbourg (km 10), Chatenois (km 18), Dambach-la-Ville (km 31), Andlau (km 48), Barr (km 61), Abbaye de Niedermunster (km 78), Klingenthal (km 85), Rosheim (km 101), and Obernai (km 109). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
- About 0.8 km after Andlau (km 48), a roughly 250 m section averaging 20% 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 24h 45m, 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 Château du Haut-Koenigsbourg (km 10) to Chatenois (km 18): the official time budget is 1h 15m for 8 km and 142 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

- 41-48 km · Rosheim → Finish: 186 m up / 191 m down; the stretch keeps rolling.
The race climbs from the gun: 280 m over the first 3.8 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 1 to km 14: net 551 m over 14 km at 4% average, its steepest roughly 250 m section averaging 16%, 708 m of climbing in total with 157 m given back. Heaviest kilometres: km 8 137 m, km 4 124 m, km 3 104 m, km 5 87 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.
The steepest wall stands between km 24 and km 30: 482 m over 5.8 km at 8% average, its steepest roughly 250 m section averaging 17%. Kilometre by kilometre: km 25 55 m, km 26 132 m, km 27 31 m, km 28 70 m, km 29 103 m, km 30 87 m. Trying to run this costs far more than it saves. Shorten the stride, lean on the poles, keep moving.
The longest descent starts at km 30 and loses 594 m by km 48 at 3% average, its steepest roughly 250 m section averaging 17%. 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 15 averages 24% over its steepest roughly 250 m section; shorten the stride, stay balanced and set speed to the ground instead of braking continuously.
The last 5.8 km drop 106 m. If anything is left in your legs, spend it here.
- The organiser lists 47 km; the published GPX measures 48 km. The technical course notes use the published GPX measurement.
- This course reaches 779 m. At the high-point coordinate, the same week historically ran 8°C to 16°C. Typical daily maximum wind was 15 km/h, reaching 24 km/h in the sample. This is climate history, not the race-day forecast; keep the shell accessible if race week looks similar.
- Even at cut-off pace you finish 4 hours 1 minute before sunset. This one is run entirely in daylight.
- Consider bringing poles. The course averages 34 m of gain per km and the longest climb averaging over 5% runs 5.8 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
- Point to point: the finish sits 6.1 km from the start as the crow flies. Sort the shuttle and your drop bag before race day.

- Sunset is 21:01 and the finish cut-off is 23:15. A runner using the full time allowance spends the final 2 hours 14 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.
- The profile does not show a clear need for poles: 15 m of gain per km. If you are not used to them, running with your hands free may be more comfortable.

158K: Sunset is 21:01 and the finish cut-off is 09:15. A runner using the full time allowance spends the final 8 hours 54 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.
