Hi, has anyone here cycled over the Pyrenees from the french side to the spanish side? I'm planning to cross the western pyrenees, heading from Pau to Pamplona, crossing via Isaba and Roncal. Basically what i want to know is how difficult will this be for a bunch of people who only bike around London and just have mountain bikes rather than road bikes. Will it be Hell on earth? We will have to go up around 1500m I think. Has anyone else done such a climb and how hard was it?
