A few years ago we went on a great 10 day bicycle tour thruogh the Dordogne Valley in Southern France. The company was called Bike Tours Direct. They are based in England and we live in South Africa but there was no problem with organising everything. Four of us were in a group af around 15 people of all degrees of fitness and capability. 50-70Km/day which is very easy. Good accomodation, great food. Self guided tours so you can go at your own pace. They take your bag ahead to the next hotel. I rode into a ditch one day and bent the bike - I had a new one within two hours. Great holiday.
