It is a route for trained cyclists along 40.3 kilometres. It has three kilometres of ascent with a gradient greater than 10%. This is excursion practicable in any time of the year.
The starting point is always from Borgo San Lorenzo, where, crossing the river Sieve, we leave the main road, turning towards Sagginale and along the valley of the torrent.
At 4.1 km we leave the valley turning in the direction of San Cresci, where, in some places, we find slopes exceed 12-14%.
At the km 7th, between the green, checks the bell tower of the church of San Cresci, which tells us that we are almost at the end of the climb. All the way long we are accompanied by farm houses and green spaces.
At the km 8.5 we arrive at Campestri, the highest point on this walk (465 meters above sea level), where a steep descent began and reveals to us the panorama of the Val di Sieve.
Then, we cross the road to Barbiana, the tiny village that recalls the story of Don Lorenzo Milani.
After the bridge of Vicchio we turn to Dicomano, immersed in the tranquillity of the Tuscan countryside. We finally reach Vicchio, birthplace of the painters Giotto and Beato Angelico, and then continue the road that leads us back to Borgo San Lorenzo.
