Here you have one example of route you can do. It is one of my favourites, as it is easy level and it has a mountain part where the dip is 4.5-6% with a rise of 840 meters high in total.
As I sais is one of my preferred routes as just gives me time to do it after work and return before dusk. The duration is of 2 hours with a total of 50,5 kilometers.
Hope you enjoy the views of Galilea village.
