The checkpoint in Sestriere was at the start of the section that had caused people the most anguish when choosing their equipment. The Strada dell’Assietta is an old military road along the top of a mountain ridge, and when combined with the gravel descent of the Colle delle Finestre, it meant doing about 40 km of dirt and gravel roads that were mostly above 2000 meters elevation. Everyone knew that it would be unpaved, but many people were not prepared for just how rough it would be on a road bike. Even the fastest people took 3 hours to traverse the short distance, but many others took a lot longer due to punctures and having to walk up and down some of the steeper sections. https://ridefar.info/races/transcontinental-race/tcr-no3/
You can miss all that out using roads. It’s paved from the top of the Finestre, you descend, then turn right and climb up to Sestriere, then descend down to Cesana Torinese, turn right again and follow that road all the way back to Susa. It’s mainly downhill.
