Tackle the steep Gradients of the Col du Granon

Whilst not the longest of climbs, what the Col du Granon lacks in length it more than makes up for in steep, punchy gradients. You will at times feel like you are barely making progress as the gradient hovers into double digits for long sections. Keep in mind if you are riding this climb in the height of summer that the blistering heat and wind which often sweeps through these parts, will make the task at hand that bit harder. The road is quieter than many of the other passes in the area so you can at least enjoy riding with relatively little traffic around.

While cycling the Col du Granon climb, you will notice roadside markers each kilometer. These indicator boards are available on the famous Tour de France climbs in the region and let you know what the next section has in store for you by means of the average gradient. No doubt you’ll be cursing the signs as they continually say, 9, 10, and even 11%! Try to let the views out across to the more famous Galibier and back down to Briançon to distract your mind from the testing average gradient. Halfway up the climb, you will hit a sustained steep section averaging over 11%. There is nothing for it but just to grind it out slowly.

Descend the way you came or take on the gravel?

As you start to spot glaciers in the distance you will really start to believe you are at the top of the world. Finally, you reach the summit. All that greets you is a small cafe and the summit sign. Take extra time at the summit to take stock of where you have come from. As only one side of the pass is paved, we have chosen to route this as an out and back ride. If you are riding a gravel or mountain bike, it is possible to continue over the top of the pass and descend down to the ski resort of Val de Prés. From there you can then head back on the D994G road to Briançon. Either way, you will have a steep descent all the way to the end.

There are not many climbs in Europe which are higher than the summit of the Col du Granon

Food and water
