How fit you need to be to cycle in France depends on the type of terrain you wish to ride. If you are looking to ride up some of the famous Tour de France climbs, you will need a reasonable amount of fitness. If you choose to join a Tour Operator, you will find most of the tours on offer will cater for all levels of fitness. France is a big country and there are so many riding options which don’t involve any mountains. Our post on the Greenways of France gives you an indication of some flatter routes on offer. Other options now also include e-bikes which means you can tackle the more difficult terrain with a little motorised help as well.
