#9: Col de la Pierre-Saint-Martin (Pyrénées-Atlantiques)
The gate of Pays Basque
(like Grand Ballon, the altitude on the sign is wrong: its 1760 m)
Recently on this thread, there were some lively discussions about the climbs in the Pays Basque. They definitely have something unique that the Tour de France should really benefit: a wonderful scenery and steep slopes that can never be found anywhere else in France. Arnostéguy and Errozaté, for example, are two passes that have an extreme difficulty, with an average gradient of 10 % and more on several kilometers. These could be the french Anglirus. But these climbs have a serious problem and it won't be fixed anytime soon: they're just very narrow. Both in ascent and descent. Which would definitely be an issue both for the organizers, who need room for the caravane and the technical vehicles, and for the riders, who don't want to risk their lives on steep and tight descents.
And that probably explains why the Tour just never went into these monsters of Iparralde: the Tour might be too big for them, even if Christian Prudhomme stated "the caravane shouldn't dictate its law over the course, it has to adapt to the way we are taking". It's a bit of a shame, but they were worthing a mention in this post, and probably some day in the future, ASO will try to adapt to these incredible climbs, and ask the authorities to make some adjustments to the road. They already did it in the past (even if some people are against these pratics).
So that's why we're going toward Hegoalde, or "south Pays Basque". And there's one climb in there that would be worthy to join the HC list. It was climbed only once in 2007, and from its spanish side (the easiest). That's right, it's a border pass. It's also an hard one on its french side. The col de la Pierre-Saint-Martin would be another welcomed addition to the Hors Catégorie climbs, and best of all, there's a ski resort not far from the pass, simply called La Pierre-Saint-Martin. And what's known is they really want to host a stage finish for the Tour de France.
By seeing the climb (from two sides), we know why.
Top: 1760 m
West side (from La Caserne, 16 km after Tardets)
Length: 18 km
Ascent: 1320 m
Average gradient: 7.3 %
Climbbybike Difficulty score: 137
North side (from La Mouline, 7 km after Arette)
Length: 18.5 km
Ascent: 1305 m
Average gradient: 7.1 %
Climbbybike Difficulty score: 132
There's something that should be notified beforehand: most part of these climbs are actually the same as the Col du Soudet, topping at 1540 m, already rated HC by the Tour twice (in 1987 and 2006). Both sides join at this pass, so you can consider the col de la Pierre-Saint-Martin as a bonus, an 3.5 km extension to this already demanding climb. To arrive into the ski resort of la Pierre Saint-Martin, it's 1.5 km after the Col du Soudet.
The west side goes like a crescendo, starting slow with 4-5 % slopes after a quite long false flat part, then starts to get really hard after Sainte-Engrace, on a road that doesn't give back all of the effort. There's also 2 kilometers at over 10 %, in between two easier parts. Then the climb becomes again really harsh up to the Col du Soudet, only to become easier after the ski resort. It's the hardest side to come up to the top.
The north side isn't that easier though. Its hard part starts 2 kilometers after La Mouline, with no less than 8 km at 9.4 % average with a kilometer at 11 %, that lead to the col de Labays (which links to the east, and could make another climb up to La Pierre-Saint-Martin). Then, the climb is much easier, the only really steep part being after passing the Soudet up to the ski resort.
The col de la Pierre-Saint-Martin has also other sides, that go through surrounding passes (Hourcère, Labays, Bouesou), but they are no harder has the two sides presented here. This is definitely as hard as the two great climbs of the Pyrénées, namely Aubisque and Tourmalet, and it also goes quite high. It's only a matter of time until the Tour stops in la Pierre-Saint-Martin, and offering to the Pyrénées another HC climb. In 2012, there were rumors for a MTF in the ski resort, but it was ultimately cancelled some time before the official announcement of the route. They might be on the spot for 2014... Time will tell.
To be perfectly honest, I initially planned Arnostéguy as being #9 on the list. But on second thought, I took Pierre-Saint-Martin as the logistic problems would be too high on Arnostéguy (and Errozate). So I decided to give them a mention anyway.
