The Jafferau is an explosive final chapter at the end of a demanding route. The climb is 5.4 kilometres and averaging 11.5%. The steep ramps featured in the 2013 Giro d’Italia when Mauro Santambrogio climbed to victory in the same time as maglia rosa Vincenzo Nibali. The weather was a disaster that day, so Colle Sestriere was taken out of the route.
Let’s hope weather god Jupiter is in a better mood this year as the Colle Sestriere is meant to be the penultimate climb of the 19th stage of the 2018 Giro.
After the start the route climbs gradually to the top of the Valli di Lanzo – a gentle warm up. The party really gets going on the Colle delle Finestre, a mountain that kicks in hard with opening gradients of 14%. The Finestre amounts to 18.45 kilometres and the last 7.8 kilometres over the top is a gravel road. The average gradient of the climb is 9.2%, while the summit is crested at kilometre 110.
Following an 11 kilometres descent the Colle Sestriere looms, a climb of 9.2 kilometres with an average gradient of 5.4% and ramps of up to 9%. The final mountain stage of the 2015 Giro d’Italia concluded with the Finestre/Sestriere combo. Leader Alberto Contador lost more than 2 minutes after being dropped on the gravel roads of the Finestre, yet his overall victory was not jeopardized. Fabio Aru took the stage honours and finished second on GC, still 2 minutes down on the now retired Spaniard.
In 2018, the route continues to the steep Jafferau, where Eddy Merckx climbed to victory in the 1972 Giro, thus cementing his overall lead which ultimately led him to winning the pink jersey that year.
