Pale rock. High roads.
A day you will
remember.
The Maratona brings riders to Alta Badia for a day on some of the Dolomites’ great roads. Above the villages, hairpins climb towards pale limestone towers and each pass opens into another mountain valley. Campolongo, Pordoi, Sella and Gardena set the scene; Giau, Falzarego and Valparola give the long route its scale.
Campolongo comes round again. Beyond Arabba the route reaches towards Selva di Cadore, then turns uphill for Giau: nearly ten kilometres of sustained climbing after a succession of high passes. Falzarego and Valparola still lie on the road home. The appeal is in that sequence, as much as in any single summit: a day spent joining the Dolomites together.

CHAPTER 010–55 KM
Around the Sella
From La Villa the road climbs towards Corvara, then continues south over Campolongo to Arabba. Pordoi follows from the eastern side. Its hairpins take the route above the valley, then the descent on the other side leads to the turn for Sella. Four passes form this opening circuit, but the roads between them give each ascent a character of its own.
Sella carries the ride into a landscape of exposed rock. The descent leads to the road for Gardena, where climbing is broken by a gentler middle section before the final rise. Over the pass, the road falls through Colfosco towards Corvara. The route has circled the massif; it now returns to a road already ridden.

CHAPTER 0255–97 KM
The long road to Giau
The second ascent of Campolongo is familiar ground with a different place in the day. Arabba follows again, but this time the route leaves the opening circuit behind, following the valley towards Cernadoi and the roads to Selva di Cadore. The long course makes room for a broader journey before its most sustained steep climb.
Giau rises from the Selva di Cadore side, through wooded bends and out towards open slopes beneath the rock towers. Its summit comes about 97 kilometres into this track. The climb changes the balance of the ride: the passes around Sella are now behind, and the remaining road must find its way back to Alta Badia.

CHAPTER 0397–139 KM
The way back to Alta Badia
The descent from Giau leads towards Pocol, where the route turns west for Falzarego. This is another long ascent, followed by the short continuation to Valparola. The two passes are close together, but they mark separate moments in the journey: Falzarego opens the crossing, Valparola sends the road back towards Alta Badia.
The descent runs towards San Cassiano and La Villa. There is one last interruption before Corvara: Mür dl Giat, a short, steep detour through La Villa. After the high passes, its scale is small and its gradient abrupt. Beyond it, the road climbs gently back towards the finish in Corvara, completing the long return from Giau.

The defining climb:
Passo Giau.
9.3%
Average gradient over 9.9 km
Giau climbs for nearly ten kilometres from the Selva di Cadore side, averaging 9.3%. Wooded bends give way to open slopes and the rock towers above the pass. It is the long course’s most sustained steep ascent, with the climb beginning after almost 90 kilometres of riding.
Its position matters as much as its gradient. Campolongo has already been climbed twice, and Pordoi, Sella and Gardena are behind you. At the top, the road opens beneath the rock towers, but Corvara is still on the far side of Falzarego and Valparola. Giau is a turning point in the day, rather than its final obstacle.
