Start riding up SR 48 road as far as Pocol (about 5 km).
Turn left and attempt the 11 km steep climb up to Passo Giau. Once on top enjoy the awe-inspiring view that stretches from Pelmo, Civetta and Marmolada massifs on the one side to all the Ampezzo peaks on the other.
A challenging descent will lead you to Colle Santa Lucia, then turn right and continue as far as the intersection with the road from Alleghe, turn right again and descend for 3 km until Cernadoi, where the 10-km long ascent to Passo Falzarego begins.
At Passo Falzarego, you may take the cable car up to Mt. Lagazuoi. An 8 minute ride will take you up to the namesake mountain inn with its spectacular view and excellent cuisine.
Descend by cable car, get back on your bike and enjoy the adrenaline of the 17 km descent back to Cortina.
