*How do you determine difficulty ratings?

It is challenging to come up with a difficulty rating system that is relevant for everyone. A very fit cyclist might consider our “Moderately Strenuous” trips to not be hard at all, while someone who exercises infrequently or is not used to cycling might find a “Moderately Easy” tour to be quite a challenge. Our bicycle tour rating system is based on the approximate fitness level of a casual recreational cyclist who rides at least once per week and rides over fifteen miles on a regular basis. If you ride less or more than this, please adjust your expectations of the tour accordingly. To flesh out the rather subjective difficulty rating, we also include the distance for each tour and a terrain description.
