Sellaronda Bike Day 2026 — autumn edition over the four passes

On Saturday 12 September 2026 the four passes that ring the Sella massif close to cars again and belong to bicycles. This is the autumn edition of the Sellaronda Bike Day, twin to the one held in June: same loop, same format, but with the light and colours of early autumn over the Dolomites.

Four passes without engines

From 9:00 to 16:00 the roads over Passo Campolongo, Passo Gardena, Passo Sella and Passo Pordoi are closed to motor traffic. It is not a race: there are no official starts, no rankings and no timing. Everyone chooses where to begin, which direction to ride and at what pace.

The organising committee recommends riding the loop anticlockwise and wearing a helmet, given the speeds reached on the descents. Closing the roads does not suspend the Highway Code, which still applies.

The route

The loop measures 51.8 kilometres with roughly 1,680 metres of positive elevation gain. It has no start and no finish: it closes on itself and can be joined from any of the villages it touches.

• Passo Campolongo (1,875 m) — the shortest climb, four kilometres from Arabba
• Passo Gardena (2,121 m) — from Corvara, in Alta Badia
• Passo Sella (2,244 m) — between Val Gardena and Val di Fassa
• Passo Pordoi (2,239 m) — the descent that brings you back to Arabba

Practical information

Arabba, the Belluno side of the Sellaronda

Of the four villages facing the loop, Arabba is the only one in the province of Belluno. The shortest climb starts here, up to Campolongo, and the longest descent ends here, down from Pordoi: it is the natural base for anyone arriving from the Agordino or the Boite valley.
