hughjateeens, well done for getting an entry. I have done both this and Trans Provence and my advice is…
Take good waterproofs. You may never need them but trust me if you do, then you really do 🙂
A set of clothes for every day of riding may seem overkill but you do work very hard and its a nice luxury.
Loads of socks.
Get your nutrition bang on ie know what works for you on long days in the saddle as doing 6 days back to back is not funny when you are hanging out.
The most important is to mellow out and look around you, it’s so easy to get caught up in everyone else mad rush but the week will be over in a flash and you want to actually experience it.
And make sure your forks are set up right, you point downhill a lot. 🙂
Enjoy
