Quite accessible for a normal training level. The first section is more shaded, the second more open. Almost at the end, turn right to climb to the Peyragudes station. You can also do it at the summit with less gradient; it's a more accessible road in good condition.

Although the climb up the Col de Peyresourde from Arreau is 18 kilometers, the slope only really steepens after Avajan, from the eleventh kilometer. You'll therefore need to save your strength for the first part to be able to tackle this Pyrenean classic.

Beautiful asphalt road whether on the Ferrere side or the Luchon side. The climb on the Ferrere side is much more pleasant. I recommend this pass.
