technical info

A very long stage, potentially nervous in the first part as the riders tackle the hills of Siena before crossing the city itself. Of note in the first section are four consecutive level crossings. The gradients soften after Torrita di Siena. The plain of Lake Trasimeno leading to Perugia is characterised by mostly straight but sometimes narrow roads. Then comes the long but not too steep climb of Casacastalda, whose descent leads directly to the finish. A very articulated and demanding road, especially on the descent.
Last km
The last kilometres are undulating and mostly downhill until the very last 1,000 m, where a rather sharp turn is located. The road features wide bends but ends in a nice long straight, slightly uphill with gradients of around 4%. The final straight is an 8 m wide roadway.
