After a thrilling and often surprising three weeks, the Giro d’Italia all comes down to this: 205km of Alpine terrain to settle the destiny of the maglia rosa. The accumulated fatigue of three weeks’ racing and several difficult Alpine days could yet see the GC favourites crumble, and this Giro has proved there’s always a surprise, a twist and turn in store.
The last of five tough outings in the mountains in this final week, stage 20 encompasses 4,500m of altitude gain, the majority of it on the showpiece climb of the Colle delle Finestre.
