Col du Coq


Bike route 548095 – powered by Bikemap 

Another steep, quiet, scenic cycling climb near Grenoble.

Col du Coq is in the Chartreuse massif to the north of Grenoble. It’s a steady, steep climb averaging almost 9% for 12.7 kms.

Half way up are two dark tunnels that were soaking and leaking inside. I always seem to hit my highest heart rate of the year cycling through dark, “uphill” tunnels. They scare me.

After the tunnels the road splits and the route takes a quieter road to the Col.

There lots of interesting stuff on the other side and I had a bigger route planned. But I was rained on twice on the way up and I decided it didn’t make sense to get on the wrong side of a mountain in case of a storm.

Happiest while cycling uphill. More enthusiastic than talented, my 2014 Challenge is to cycle 50 great rides, slowly.


  1. Si c’était aujourd’hui, on a failli se croiser ! J’ai changé d’avis finalement car je voudrais le faire par beau temps. J’étais en face (Belledonne).
