Greetings and Bonne Route GR65 from Sydney. I did this last year in July/August. Setting a distance is unreasonable and you will miss festivals and saint's days that pop up along the way. Also, the path is variable. Muddy, Rocky, up, full of cows, French cows are friendly. I never managed 25 km a day, but I'm a fat old woman. But I saw a great festival in Estaing, (and met Valerie d'Estaing's grandson, looks just like him.) and back tracked to another festival in a village famous for it's giant wolf. Too much planning gets in the way of the experience. For booking in advance, buy yourself a French sim card, I bought a French phone with a keypad, Yeah! Cheaper 49 euro and easier. I have to say, I found the people who insisted on going a set distance every day a real pain. They were mostly French, who treated it like the tour de France. I did walk with an 83 year old Frenchwoman who was faster than me for a few days. The Miam Dodo 'Le Puy à Cahors' is excellent.If you pm me, I'll send you it. Never had a bad meal always take the DP option, sometimes the flies were worse than in Australia! The French haven't discovered screened windows or Aerogard. The signs on this route are very well maintained. Carry apples and sugar for all the horses and cows you will meet. One or two over protective dogs along the route. Avoid. Have Fun, Practise yr French!
