Side Pla d'Adet
It's a short climb, 10km approx, but most of them very hard, that's why this is usually the final climb of a Tour stage. The gradient here is a little bit harder than mountains nearby like Peyresourde, Aspin...
In the middle of the terrible >
Since the beginning, the impact of the '>' dominating Saint Lary, makes first 3km very tough, at 10%, no rest. In fact, it's only when you get to Soulan, middle of the climb, when the gradient becomes easier for a short time, 5-6%. Leaving Soulan, again very hard, 9-10% since you reach a left bend, which can drive you to the Col du Portet, or finish atop Pla d'Adet.
Top of Pla d'Adet at Tour'05
Since that point, almost everything very hard, but last 2km,, at 6-7%, are the only place where you can breathe. It's a very explosive climb, I recommend a 39x25 at least, entire kilometers at 10% is a serious challenge. My best this year was 50' approx.
The day I was there, I couldn't imagine what this Portet was. First of all, long climb tis one with 16km, very constant and steep. First 8km are the first of Pla d'Adet climb, and then we leave that road to take another one directly to 2215m.
Last km of Portet
So all explained above is valid...til you reach the junction, where the gradient remains at 8% almost always. The point is the asphalt: it is horrible, if there is. At least half the climb is simply road, no asphalt. The road is not bad...but you must be careful. Only the last km is harder, and the surface is poorer. Overall, hour and a half climbing to nowhere.
