The difference between the behaviour and handeling,laden and unladen, over rough terrain is considerable. Acceleration is slower, which is not of great importance.but braking is much more sluggish which can be dangerous unless you are used to it. Some of the rough tracks through the Pyrenees and Navarre are not the places to get accustomed to a change in behaviour. Whichever type of bicycle, the prudent pilgrim will seek to reduce weight as much as possible. It should always be borne in mind that travel on the Camino in June, July and August will require a high intake of fluid.
Water is a substantial addition to the overall load.
Most pilgrims who contemplate riding to Santiago will possess a bicycle and providing it is a reasonable quality tourer or M.T.B., it will be adequate. Those without a bicycle or cycling experience need to do some research. If you can find one, perhaps the best option is to find a sound dealer, preferably one who handles maintenance as well, and seek his advice. The latter has a number of cycling pilgrims in its ranks who will be happy to help. Cost is a consideration.
