• Keen on this, what's the deal with camping? Carry a lightweight tent and sleeping bag or just a bivvy?

    Realistically how fit do you think you'd have to be? Monday to Thursday looks like some pretty serious riding.

    I'm thinking of a tent, especially as it's the Alps, and you don't want to be shivering in sleet in air temps just above freezing (which is perfectly possible even in summer in the Alps).

    The 2nd day to Bourg d'Oisans is probably the hardest, 2 +1000m cols. You'd have to have done some miles, for sure, but you wouldn't need to be super-fit. If you break it down, it's only 50k in the morning, and 50k in the afternoon. As long as you get on the road before 8am, it shouldn't be problem.

    However, if you're pulling camping gear, you want 30 X 28 or similar, otherwise you won't make it.
