FOCUS ON THE WORLD OF OUTDOOR HORSERIDING
Here is a selection of the numerous websites that I have spent many hours reading...

Association Cavaliers au Long Cours (CALC) – the aim of this association is to encourage riding on horseback: forums, newsletter, etc. This is the association that got me in the saddle so that I could take off on my adventure. In 2011 I took part in a forum not far from Niort, France.

Website put together by Emile Brager, co-founder of the CALC. Emilie has ridden up the entire continent of America, from Patagonia to Alaska. She has also published a book that is a reference work for long rides:
Techniques du voyage à cheval, Editions Nathan (French only).
SAME THING, AMERICAN COWBOY STYLE

Association of American outdoor horse riders

Advice from the pack horse experts

Site presenting the experiences of long riders

The cowboys’ website!
