That’s a nice, long, steep, cyclospore-like circuit. If part of the circuit will take you to the plain near the town of Lannemezan, you will then discover 2 majestic passes: Col du Port de Bales and col de Peyresourde. These two passes were often the justice of the peace of the Pyrenean stages of the Tour de France. At the top of each, you can enjoy a gourmet break in summer.
