What the weather is usually like here
- Over the last 5 years this week typically ran 14°C to 25°C here, with a high of 33°C and a low of 7°C.
- 43% of those days saw rain. A real forecast lands about two weeks out and will appear here then.
- Typical daily maximum wind was 17 km/h (a light breeze), with 30 km/h the highest value in the sample.
- It has been hot here before: if race week trends warm, scale your fluid plan up.

The first 5 km climb 165 m and then drop 186 m. Do not attack the opening climb in the crowd, and do not brake your way down the drop behind it.
The backbone of the course runs from km 18 to km 28: 747 m over 11 km at 7% average, its steepest roughly 250 m section averaging 20%. Heaviest kilometres: km 20 107 m, km 19 104 m, km 28 98 m, km 27 97 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 82 and km 97: net 619 m over 14 km at 4% average, its steepest roughly 250 m section averaging 21%, 882 m of climbing in total with 263 m given back. Heaviest kilometres: km 90 117 m, km 87 109 m, km 91 107 m, km 93 75 m. By the time you start it, about 69% 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 longest descent starts at km 111 and loses 620 m by km 125 at 4% 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 drop at km 28 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 6 km drop 136 m. If anything is left in your legs, spend it here.
You reach the climb after Saint Julien des Chazes with about 860 m of descent already in your quads; treat its first half as recovery effort.
You reach the climb after Monistrol with about 884 m of descent already in your quads; treat its first half as recovery effort.
A steep pitch starts within about 1.9 km of Saint Privat; keep the stop short and do not enter it on cooled-down legs.
You reach the climb after Alleyras with about 895 m of descent already in your quads; treat its first half as recovery effort.
The leg from Alleyras to Lac du Bouchet is long and unsupported: 15 km and 748 m of climbing with no aid in between, so leave Alleyras with full capacity.
A steep pitch starts within about 0.9 km of Lac du Bouchet; keep the stop short and do not enter it on cooled-down legs.
- The organiser lists 140 km; the published GPX measures 137 km. The technical course notes use the published GPX measurement.
- This course reaches 1428 m. At the high-point coordinate, the same week historically ran 11°C to 22°C. Typical daily maximum wind was 17 km/h, reaching 32 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 21:35, 2 hours 35 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 44 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.
- 13% of the course is steep descent. Increase your cadence instead of braking, or your quads go early.
- Point to point: the finish sits 28.1 km from the start as the crow flies. Sort the shuttle and your drop bag before race day.
Course-profile notes are generated from GPX grade data; terrain, rules, aid stations and weather are added only when separately sourced.

Lac du Bouchetkm 100
- Take hot food you digest easily and top up fluids.
- Crew access is allowed here.
- A heavy leg is next: 12 km with 515 m of climbing.
- The longest stretch between official aid stations runs from Saugues (km 0) to Saint Julien des Chazes (km 18): 18 km, with 371 m of climbing in between. Top up at Saugues and size what you carry to the expected duration and your own drinking rate.
- Drinks only, no food, at Saint Julien des Chazes (km 18) and Bains (km 116). 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.
- Sommet de la Durande (km 29) is a timing point only, with nothing on the table. Load up as you leave Lespitalet.
- Hot food is served at Saint Jean Lachalm (km 73) and Lac du Bouchet (km 100). 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 Lespitalet (km 25) and Prades (km 41) and 5 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 Saint Jean Lachalm (km 73). 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 Prades (km 41), Monistrol (km 56), Saint Privat (km 64), Saint Jean Lachalm (km 73), Lac du Bouchet (km 100), and Saint Christophe sur Dolaizon (km 123). 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 Les Chibottes (km 133), leaving 7 km to the finish. After that you are on what you carry.
- The heaviest leg runs from Prades (km 41) to Monistrol (km 56): 15 km with 802 m of climbing. Treat it as the slowest part of your day and get your food out before it.
- Medical support is available at Prades (km 41), Monistrol (km 56), Saint Privat (km 64), Saint Jean Lachalm (km 73), Alleyras (km 85), Lac du Bouchet (km 100), and Le Puy en Velay (km 139). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
- About 2 km after Saint Privat (km 64), a roughly 250 m section averaging 34% begins. Choose food you know you digest easily and fill the bottles, then enter the climb at a controlled effort.

- 0-5.2 km · Start → Traversée loire - Mélussac: 52 m up / 244 m down; the stretch descends.
- 5.2-13 km · Traversée loire - Mélussac → Charentus: 206 m up / 225 m down; the stretch keeps rolling.
- 13-15 km · Charentus → Tunnel de Valhory: 137 m up / 7 m down; the stretch climbs.
- 15-17 km · Tunnel de Valhory → Le Riou: 134 m up / 111 m down; the stretch keeps rolling.

- 22-28 km · Les Chibottes → Finish: 105 m up / 257 m down; the stretch descends.
The first 2.2 km drop 112 m. Fresh legs make it feel free, but you climb every metre of it back.

The longest descent starts at km 19 and loses 252 m by km 27 at 3% average, its steepest roughly 250 m section averaging 12%. 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 0 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 3.3 km drop 136 m. If anything is left in your legs, spend it here.
- Sunset is 21:33, 14 hours 33 minutes after the gun. If your target time is longer than that, carry a headtorch whether or not the rules demand one.
- Poles are optional: 29 m of gain per km. Bring them to protect your legs, not to gain speed.
- Point to point: the finish sits 8 km from the start as the crow flies. Sort the shuttle and your drop bag before race day.
