My experiences on the Peyresourde highlights why you often need to revisit a climb more than once. In 2012 it was the final climb in a tough Etape de Tour. I was suffering, see blog. I remembered nothing of it, just a blurred view of my handlebars. In 2014 I spent more time here (including the Peyraguides route and the back way through the village of Cathervielle). A beautiful place.
