More like deux Vieux de la montagne – a very appropriate name. … l certainly felt like an old man of the mountains after this one. La Balme is almost roadside (attractive for sore legs) but lower and facing pretty much south – it turned into an oven in the 30C heat.
Vieux de la montagne takes the pillar, chimney and “slab” left of the huge roofs. Only 6 pitches, but the 6bs felt like 6cs, and the 6cs felt like 7as in the heat and polish. It all added up to a route too far, and turned into a fair bit of A0! My toes have never been so sore!
