In the genuine calamity category, here is the super collet.
Hard from the start, very hard afterwards (almost 5km around the 9％) and only calms down once past the collet station.
The quality of the route is good, mainly in the woods, so not unforgettable in terms of scenery.
Otherwise, it's well worth the effort.
Welcome to belledonne
Dans la catégorie authentique vacherie, voici le super collet.
Dur dès le début, très dur ensuite (quasi 5km autour des 9％) et ne se calme qu'une fois passé la station du collet passé.
La qualité de la route est bonne, essentiellement dans les bois, donc pas inoubliable au niveau paysage.
Sinon ça vaut vraiment le coup.
Bienvenue en belledonne
The quality of the road is excellent, with some nice stretches of fairly shaded terrain. However, be careful on the descent past the village, as the little bridge is flooded with potholes.
Otherwise, it's well worth the effort.
Qualité de la route excellente, de beaux passages assez ombragés. Attention tout de même après la descente une fois passé le bourg, le petit pont est inondé de nid de poule.
Sinon ça vaut vraiment le coup.
A great climb with the most challenging part in the first half. Road conditions range from ‘brand new’ to ‘good enough’. The viewpoint at the finish is disappointing, but there are nice viewpoints along the way. The starting point is the same as for Le Pleynet.
One of the few climbs in the region around Grenoble that I had never done by bike (but by car, to go skiing at this nice resort :-). It is indeed surprisingly difficult, and especially regular in its difficulty: no respite until you reach the end of the Collet d'Allevard resort. Then a very short descent and the last few kilometres are much less steep until Super Collet.
Very nice views after the first kilometres on Allevard and its surroundings, and fantastic panoramas once arrived at the Collet. Between the two, you are almost permanently in the middle of the forest. Weakness: the road is in a rather average state, which surprised me. On the cliff side, there are a lot of small parts of the road that have collapsed and cracks in which the wheels can get caught if you are inattentive. You have to be careful on the way down, which is very fast.
Une des rares montées de la région autour de Grenoble que je n'avais jamais faites à vélo (mais bien en voiture, pour aller skier à cette station bien sympa)… jusqu'à aujourd'hui. :-)
C'est effectivement étonnamment difficile, et surtout régulier dans la difficulté : aucun répit jusqu'à ce qu'on arrive à la fin de la station du Collet d'Allevard. Ensuite, une très courte redescente et les derniers kilomètres bien moins pentus jusqu'à Super Collet.
Très beaux points de vue après les premiers kilomètres sur Allevard et ses environs, et fantastique panorama sur la Chartreuse, les Bauges et la cluse de Montmélian une fois arrivé au Collet (table d'orientation). Entre les deux, on est quasiment en permanence en pleine forêt. Point faible : la route est dans un état assez moyen, ce qui m'a surpris. Côté falaise, pas mal de petites parties de route affaissées et de lézardes, dans lesquelles les roues peuvent se prendre si on est inattentif. Il faut faire attention à la redescente, très rapide.
Fine and tough climb. At some points high gradient that alternates with more manageable ones.
Fijne en pittige klim. Op sommige punten hoog stijgingspercentage dat wordt afgewisseld met meer haalbare kaarten.
The climb to Collet d'Allevard is a short but dry climb.
About 12km long, on a nice wide road with a good surface, the climb is particularly difficult because of its high gradients.
The laces are far from each other, which makes the relaunching quite difficult, no respite from the slope before the 11th kilometer.
As for the scenery, as the climb is lined with trees, you will have to take advantage of a few gaps and especially the final stretch at the station to see the valley.
If you still have some juice left, you can continue to the Super Collet parking lot 4 kilometers further with relatively modest gradients and a lesser quality surface when I went there.
If you want to warm up, I advise you to start from the parking of the small lake ST clair at la Rochette 10km before, picnic corners for the return and especially sanitary facilities and drinking water.
Good road and be careful
La montée au Collet d'Allevard est une montée courte mais sèche.
D'une longueur d'environ 12Km, sur une belle route large avec un bon revêtement, l'ascension est particulièrement difficile de par ses pourcentages élevés.
Les lacets sont éloignés les uns des autres ce qui rend assez pénible les relances, pas de répit de pente avant le 11ème kilomètre.
Question paysages, vu que la montée est bordée d'arbres, il faudra profiter de quelques trouées peu nombreuses et surtout le final à la station pour apercevoir la vallée.
S’il vous reste encore un peu de jus, vous pouvez prolonger jusqu'au parking du Super Collet 4 kilomètres plus loin dans des pourcentages relativement modestes et un revêtement de moindre qualité lorsque j’y suis allé.
Si vous voulez vous échauffer, je vous conseille de partir du parking du petit lac ST clair à la Rochette 10km avant, Coins pique-nique pour le retour et surtout sanitaires et eau potable.
Bonne route et Soyez prudents
Cycled this summer. Beautiful climb. From Collet d'Allavard you can continue to climb to Super Collet. Still about 4 km extra climb, although at lower percentages. Makes it in any case even harder. Good luck!
Deze zomer gefietst. Mooie klim. Vanaf Collet d'Allavard kun je doorklimmen naar Super Collet. Nog ongeveer 4 kilometer extra klimmen, weliswaar tegen lagere percentages. Maakt het in ieder geval nog zwaarder. Succes!
