Starting from Borgo San Lorenzo, the largest town in Mugello, as well as the main hub of services in the whole area, the route takes you towards Florence along the via Faentina. After crossing the river, leave the provincial road, immediately turning left in the direction of Sagginale. As you cross the valley floor of the River Sieve the road widens, but traffic is light.
As you leave the valley bottom and turn right in the direction of San Cresci, the traffic is virtually nonexistent. The road is much narrower, and the terrain rougher with an increasingly rockier road surface. The slopes also increase in gradient, at some points the road climbs in excess of 12-14%. The reward for a 5.9 km climb comes as a very welcome, 100-meter flat section, allowing time to catch your breath. Hereafter the route starts to ascend again but offers reprieve in the form of a few gentler slopes. At 7km in the bell tower of the beautiful church of San Cresci appears among the trees indicating that we are almost at the end of the climb. A further 300 meters takes us to the start of a much-needed downhill stretch. Villas and farmhouses dot this area where time seems to flow more slowly than in the city.
