Course map and elevation profile
What the weather is usually like here
- Over the last 5 years this week typically ran 18°C to 30°C here, with a high of 37°C and a low of 14°C.
- 9% of those days saw rain. A real forecast lands about two weeks out and will appear here then.
- Typical daily maximum wind was 12 km/h (a light breeze), with 18 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 05:54, 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 race climbs from the gun: 957 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 0 and km 8: net 1375 m over 7.9 km at 17% average, its steepest roughly 250 m section averaging 39% on the GPX trace, 1541 m of climbing in total with 166 m given back. It tops out at 1800 m. Heaviest kilometres: km 4 296 m, km 5 289 m, km 3 222 m, km 2 189 m. Running is not on the menu at this grade; settle into a hike from the bottom and load the poles, short steps.
The backbone of the course runs from km 31 to km 43: 1612 m over 12 km at 14% average, its steepest roughly 250 m section averaging 54% on the GPX trace. It tops out at 2437 m. Heaviest kilometres: km 43 364 m, km 42 295 m, km 41 222 m, km 37 179 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 late climb from km 91 to km 95: 635 m over 4.1 km at 15% average, its steepest roughly 250 m section averaging 27%. Kilometre by kilometre: km 92 160 m, km 93 220 m, km 94 129 m, km 95 140 m. By the time you start it, about 88% of the day's climbing is behind you. This is a hiking section, not a running section. Set the rhythm as a hike and move up without burning matches.
The longest descent starts at km 95 and loses 1190 m by km 108 at 9% average, its steepest roughly 250 m section averaging 24%. 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 43 averages 44% 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 291 m. If anything is left in your legs, spend it here.
You reach the climb after Calacuccia with about 607 m of descent already in your quads; treat its first half as recovery effort.
You reach the climb after Ballone with about 507 m of descent already in your quads; treat its first half as recovery effort.
The leg from Ciattarinu to Inzecche is long and unsupported: 15 km and 605 m of climbing with no aid in between, so leave Ciattarinu with full capacity.
A steep pitch starts within about 0.9 km of Inzecche; keep the stop short and do not enter it on cooled-down legs.
You reach the climb after E Grotelle - chez Téo with about 430 m of descent already in your quads; treat its first half as recovery effort.
- The organiser lists 110 km; the published GPX measures 108 km. The technical course notes use the published GPX measurement.
- This course reaches 2459 m. At the high-point coordinate, the same week historically ran 8°C to 17°C. Typical daily maximum wind was 10 km/h, reaching 22 km/h in the sample. This is climate history, not the race-day forecast; keep the shell accessible if race week looks similar.
- Poles are strongly recommended for this profile. The course averages 66 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.
- 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.
- 23% 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 2459 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 13 km of the course sits above 1800 m. The longest unbroken stretch up high is 4.6 km and the high zone spans roughly km 78 to km 83.
Course-profile notes are generated from GPX grade data; terrain, rules, aid stations and weather are added only when separately sourced.

Alzukm 99
- Take hot food you digest easily and top up fluids.
- Crew access is allowed here.
- The longest stretch between official aid stations runs from Ciattarinu (km 60) to Inzecche (km 75): 15 km, with 613 m of climbing in between. Top up at Ciattarinu and size what you carry to the expected duration and your own drinking rate.
- Drinks only, no food, at Bocca Capizzolu (km 26) and Bocca a Soglia (km 84) and 1 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.
- Pinadellu (km 21) is a timing point only, with nothing on the table. Load up as you leave Aleri.
- Hot food is served at Calacuccia (km 33) and Ballone (km 48) and 4 more. 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 Aleri (km 13). 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 Ciattarinu (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 Aleri (km 13), Calacuccia (km 33), Ballone (km 48), Ciottulu di i mori (km 53), Ciattarinu (km 60), Inzecche (km 75), E Grotelle - chez Téo (km 88), Tragone - chez César (km 94), and Alzu (km 99). 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 Alzu (km 99), leaving 11 km to the finish. After that you are on what you carry.
- The heaviest leg runs from Calacuccia (km 33) to Bocca Crucetta (km 44): 11 km with 1788 m of climbing. Treat it as the slowest part of your day and get your food out before it.
- Medical support is available at Aleri (km 13), Calacuccia (km 33), Ciattarinu (km 60), Inzecche (km 75), E Grotelle - chez Téo (km 88), Alzu (km 99), and Corte (km 111). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
- About 2 km after Ballone (km 48), a roughly 250 m section averaging 36% 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 Calacuccia (km 33): the official time budget is 10h for 33 km and 2406 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

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 20 and loses 1153 m by km 32 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 8 averages 35% 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 3.9 km drop 190 m. If anything is left in your legs, spend it here.
- The organiser lists 33 km; the published GPX measures 32.2 km. The organiser lists 2400 m of climbing; the published GPX measures 3050 m. The technical course notes use the published GPX measurement.
- This course reaches 1817 m. At the high-point coordinate, the same week historically ran 12°C to 22°C. Typical daily maximum wind was 10 km/h, reaching 22 km/h in the sample. This is climate history, not the race-day forecast; keep the shell accessible if race week looks similar.
- Start 05:00, sunrise 05:54: the first 54 minutes are run in the dark. The headtorch goes on your head at the start, not in your pack.
- Sunset is 21:01, 16 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 95 m of gain per km and the longest climb averaging over 5% runs 7 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
- 35% of the course is steep descent. Increase your cadence instead of braking, or your quads go early.
- The high point is 1817 m. Coming from sea level, your heart rate and breathing shift at the same pace, so leave yourself room in the first hour.

Key decision points
Alerikm 13
- Collect food and fluids and leave within 60-90 seconds.
- Crew access is allowed here.
- A heavy leg is next: 7.4 km with 455 m of climbing.
- Cut-off: 5h 20m after the start.
Alzukm 20
- Take hot food you digest easily and top up fluids.
- Crew access is allowed here.
- A heavy leg is next: 13 km with 414 m of climbing.
- The longest stretch between official aid stations runs from Corte (km 0) to Aleri (km 13): 13 km, with 1555 m of climbing in between. Top up at Corte and size what you carry to the expected duration and your own drinking rate.
- Hot food is served at Alzu (km 20). 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 Aleri (km 13). 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 Aleri (km 13) and Alzu (km 20). 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 Alzu (km 20), leaving 13 km to the finish. After that you are on what you carry.
- Another heavy leg runs from Aleri (km 13) to Alzu (km 20): 7 km with 455 m of climbing. Treat it as the slowest part of your day and get your food out before it.
- Medical support is available at Aleri (km 13), Alzu (km 20), and Corte (km 33). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
- Relative to distance and climbing, the tightest official time budget runs from Start to Aleri (km 13): the official time budget is 5h 20m for 13 km and 1700 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

The published GPX measures 17 km with 658 m of climbing, 39 m per km. The course sits between 387 m and 812 m of altitude. 83% of the gain sits in the first half.
The first 1.5 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 3 to km 8: net 417 m over 5.6 km at 7% average, its steepest roughly 250 m section averaging 24%, 485 m of climbing in total with 68 m given back. Kilometre by kilometre: km 4 160 m, km 5 186 m, km 6 23 m, km 7 30 m, km 8 49 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 8 and loses 405 m by km 14 at 8% average, its steepest roughly 250 m section averaging 23%. 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 drop 24 m. If anything is left in your legs, spend it here.
- This course reaches 812 m. At the high-point coordinate, the same week historically ran 15°C to 27°C. Typical daily maximum wind was 12 km/h, reaching 18 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, 3 hours 1 minute after the gun. If your target time is longer than that, carry a headtorch whether or not the rules demand one.
- Consider bringing poles. The course averages 39 m of gain per km and the longest climb averaging over 5% runs 5.6 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.
