The stage virtually climbs from the start, as the riders enter the Passo Sommo at kilometre 5. The 15.7 kilometres at 7.3% is followed by a long descent and a section in the valley before the ascent to Lago Santa Colomba commences after 53 kilometres.
The 5.6 kilometres climb averages 7.1% before the Tour of the Alps winds its way along both sides of the Cembra Valley, first on descent and then on ascent. The route continues to go up and down until reaching the Fiemme Valley, where the riders tackle the Pramadiccio Pass from Cavalese.
The Passo di Pramadiccio adds up to almost 10 kilometres and the average gradient sits at 6.1%. The sixth and seventh kilometres go up at 9.5%, which is a good place to strike as the climb levels out considerably after that section.
The Pramadiccio is crested 15 kilometres from the finish line before a fast descent leads onto a flat section, while the last 3 kilometres run slightly uphill.
The first three riders on the line gain time bonuses of 10, 6 and 4 seconds, while the intermediate sprints come with 3, 2 and 1 seconds.
