Col du Soulor

Col du Soulor (elevation 1474 m) is a mountain pass in the Pyrenees in France, linking Argelès-Gazost with Arthez-d'Asson. It connects the Ouzom and Arens valleys. A road leaves the pass to the west to reach the higher Col d'Aubisque.

The road over the col is regularly used in the Tour de France cycling race, normally in conjunction with the Col d'Aubisque.

Starting from Argelès-Gazost (east), the Soulor is 19.5 km. It rises 1019 m, an average gradient of 5.2%. It gets tough after Arrens-Marsous with stretches at 10% or steeper.

The col can also be reached from the north, via the D126. Starting from Arthez-d'Asson, the ascent is 22 km long. Over this distance, the climb gains 1074 m, at an average of 4.9%.

Tour de France
The Col du Soulor was first used in the 1910 Tour de France and was most recently featured in the 17th stage of the 2010 Tour de France, as a category 1 climb.

The Col du Soulor is also crossed during the passage over the Col d'Aubisque. When this route is used, for example in stage 16 of the 2012 Tour de France, it is often not a categorized climb, since the amount of re-ascent from the west is relatively small. It has, however, been a categorized climb on 12 occasions, including in 1982 as a hors catégorie climb.
