I know it is a bit early as the 2016 event hasn't even taken place yet, but I thought I'd put it out there early. The 2017 Gran Fondo final (formerly Masters's World Champs) will be held in Albi France in 2017. I am a native of the city and the company I work for will be offering either a full 10 day cycling trip to the event including accommodation, airport pickups, pre riding of the course etc. Needless to say I personally know the area and courses well as they are literally my back yard.
Feel free to contact me if you are planning on attending the Gran Fondo finals, or contact the company directly for more info on what we can provide. http://www.cmitours.com
