We have learned a new meaning for the term "undulating", but to be fair, we knew in advance that Tuscany is hilly. If you wish to cycle every km of this trip, then a reasonable level of fitness will be required. That said, the effort is well worth while. The scenery is fantastic. The road surfaces are excellent. The gravel paths are great fun and the hill top villages and towns are stunning. We were blessed with the weather to match and a fantastic group of people to share it with.
