[recycled sixtie]

Hi David, it has been about twelve years since I completed Wainwrights Coast to Coast in the UK. It was a total of 200 miles but divided it into four different time frames. I have no idea what Mont Blanc hiking is like or what the trails are like but these are my tips from what I did. Hiking poles. Either one or two are very useful for balance. They also take the weight off your feet going down hills and also useful as a probe for depth of water or mud.

Shoes or hiking boots? Hiking boots tend to be heavy but sometimes necessary for depth of water or mud. Goretex / waterproof footwear is a must. If depth of water or mud is not a problem then trail runner shoes are lighter and more comfortable.

You mentioned having your bags shipped to the next overnight stay. I highly recommend that. Having said that a light backpack with essentials of food and first aid would be great. For example special blister bandaids, water and snacks.

The longest days I did were 22 miles. If you can readily hike five or six miles then ten is not too much of a stretch.

Enjoy your trip!
