I'm a teenager who loves doing the most difficult climbs possible, so I obviously took this side, and it was HELL. The first few kilometres were fine, fairly even and not very steep, but once you got past virieu-le-petit it was terrible. For the remaining 4km or so you never go below 10% with one km at 15% and a long ramp that must be between 20 and 25%, I felt a little faint in this one (I already had a bunch of km in my legs and I do road with a mountain bike) but after this big ram... read more

Made for both gravel and tubeless road bikes. If you like climbs, it's all about the mind. The little shortcut at virieu le petit already gives you an idea of what you're in for at the end of the climb to the saddle!

Fait en gravel et en vélo route tubeless. si on aime les montées, tout se joue au mental. Le petit raccourci à virieu le petit donne déjà un aperçu de se que l'on va subir à la fin de la montée vers la selle !

What a beast of a col. Harping, sweating, stomping. If you don't spin the pedals you're at an instant standstill. When you cycle out of the forest, it's enjoyment and you're right at the top. You MUST have done this one!

Wat een beest van een col. Harken, zweten, stampen. Als je de pedalen niet ronddraait sta je meteen stil. Als je het bos uit fietst, is het genieten en ben je direct boven. Deze MOET je gedaan hebben!

For the remaining 4km or so you never go below 10% with one km at 15% and a long ramp that must be between 20 and 25%, I felt a little faint in this one (I already had a bunch of km in my legs and I do road with a mountain bike) but after this big ramp we've done most of the work and the summit arrives relatively quickly. The view is well worth it, you can see Mont Blanc and all the surrounding area. Conclusion: the hardest climb of my life by a long way compared with, say, Mont du Chat (but by a VERY LONG way), but a magnificent visual reward at the top.

Je suis un adolescent qui adore faire des montées les plus difficiles possibles donc j’ai bien évidemment prit ce versant, et c’était un ENFER. Les premiers kilomètres ça passe, pente assez régulière et pas très élevée, mais une fois passé virieu-le-petit c’est terrible. Jusqu’à environ 4km restants on ne descend jamais en dessous des 10% avec un km à 15% et une longue rampe qui doit être entre 20 et 25%, j’ai fait un petit malaise dans celle-ci (j’avais déjà un paquet de km dans les jambes et je fais de la route avec un vtt) mais après cette grosse rampe on a fait le plus gros du travail et le sommet arrive relativement vite. La vue en vaut largement la peine, on voit le mont blanc et tous les alentours. Conclusion : monter la plus difficile de ma vie de très loin par rapport par exemple au mont du chat (mais vraiment de TRÈS LOIN) mais magnifique récompense visuelle au sommet

For us, this climb started from Champagne Valromey. Without expectations and without a battle plan, we approached the climb and enjoyed the warm weather. When we arrived in Arviere en Valromey, the climbing began. Although we are used to some climbing, this climb surprised us enormously. After some tough kilometres we soon had to switch to the lightest gear and changing gears was no longer an option. Halfway up the climb, very steep kilometres pile up. Walls are the only way to stand, zigzagging is the solution. (I dare you;)). We found some cooling in the shadows of the trees. Take plenty of water with you. We have spotted only 1 water point. Motor vehicles can be counted on one hand. Leaving the forest behind us, the landscape changes to meadow and open fields with views of other mountain peaks. It remains steep. Arriving at the top, you enjoy a beautiful view of the Lac de Bourges. You can eat there and recover from the shock.

Voor ons begon deze beklimming vanuit Champagne Valromey. Zonder verwachting of strijdplan gingen we de klim tegemoet en genoten we van het warme weer. Aangekomen in Arviere en Valromey begon het ware klimwerk. Hoewel we wel wat gewend zijn verraste deze klim ons enorm. Na al wat stevige kilometers moesten we als snel naar het lichste verzet en schakelen zat er vanaf dat moment niet meer in. Halverwege de klim stapelen zeer stijle kilometers zich op. Muren zijn het . Staan kan niet, zigzaggen is de oplossing (Ik daag je uit;)). Enige verkoeling vonden wij in de schaduwen van de bomen. Neem voldoende water mee, wij hebben slechts 1 waterpunt gespot. De motor voertuigen onderweg zijn op een hand te tellen. Het bos achter ons gelaten verandert het landschap naar weide en open vlakte. Met het uitzicht over andere bergtoppen weet je dat het niet lang duurt. Het blijft stijl. Aangekomen op de top geniet je van een prachtig uitzicht op de Lac de Bourges. Je kan daar lekker eten en van de schrik bekomen.

Contrary to what many people think, it is not the route from Artemare, but from Tallisieu la "Directissime"; or the most direct route from the foot to the top of the Grand Colombier. Where the first 7 km from Artemare still very easy, you have from Tallisieu immediately spicy parts. Also because you can always take a short cut from the D105. Actually, the advice here is to always take the roads/entrances on the right-hand side of the D105 to drive the most direct route. Especially the part from Ouche to Chavornay is a direct hit and already in the double digits. In Virieu le Petit starts the well-known tough part, but here too is a surprise: the generally known route is via the D120C, where the road slowly gets steeper. However, 1 turn earlier you can already turn right and shorten a piece towards the D120C. This abbreviation means that here you already have to face sections of 20-25% When you get back on the D120C, this part feels like false flat, while here it's just up to 10 percent! The rest of the climb is familiar and the same as the Artemare route.

In tegenstelling tot wat is vele denken is niet de route vanuit Artemare, maar vanuit Tallisieu la "Directissime"; oftewel de meest directe route van de voet tot de top van de Grand Colombier. Daar waar de eerste 7 kilometer vanuit Artemare nog erg makkelijk zijn, heb je vanuit Tallisieu al meteen pittige stukken. Ook omdat je hier steeds een korte afkorting van de D105 kan pakken. Eigenlijk is het advies hierbij, steeds de wegen/inritten aan de rechterkant van de D105 pakken om de meest directe route te rijden. Vooral het stuk van Ouche naar Chavornay hakt er al meteen in en is al in de dubbele cijfers. In Virieu le Petit begint het bekende zware stuk, echter ligt ook hier een verrassing: de algemeen bekende weg is via de D120C, waarbij de weg langzaam steiler word. Echter kan je 1 afslag eerder al naar rechts en kort je weer een stuk af richting de D120C. Deze afkorting betekend dat je hier al stukken van 20-25% voor je kiezen krijgt! Wanneer je dan weer op de D120C komt, voelt dit stuk als vals plat, terwijl het hier gewoon tegen de 10 procent is! De rest van de klim is bekend en hetzelfde als de route van Artemare.
