It may not be the hardest Col to climb in the area - but it is one of the best known. According to Wikipedia the category 3 climb it has been included in the Tour de France 41 times since since 1911.
Officially starting from Gex (620m) the 11.8 km climb averages 6%, increasing to 8%, as it finishes at 1323m.
But it is a classic climb - and the chart tells a telling story. The 703 m climb is relentless with no flat section or descent en route for a breather.

GPS advises we cycled over 70 km and to be confirmed the best part of 1000 m of climb on my introduction to Col climbing... but for the real stuff try looking at this blog of a local Col climber euphemistically described as an "enthusiastic amateur".
