Heiden-Piuro (Valchiavenna)
Stage Overview
Commentary David Loosli
On the fourth day, the route of the Tour de Suisse 2025 heads over an Alpine pass for the first time. At 2,113 metres above sea level, the Splügen Pass is the great obstacle of the day. It is the first chance to pave the way for overall victory in the general classification. This stage is sure to show who is among the favourites and who is already out of contention. Another special feature of the day is the finish in neighbouring Italy, more specifically in Piuro in Valchiavenna.
