Overview

• Racing starts at 13:30 with a neutralized roll-out from San Mamés and a launched start near Loiu, with the finish on Gran Vía expected around 17:20 after re-entering the city via the Euskalduna bridge.
• The 157–157.4 km route crosses Bizkaia over Unbe/Laukiz, Sollube, Balcón de Bizkaia and Morga, features two ascents of El Vivero from Galdakao, and introduces the steep Pike Bidea climb (2.3 km at 8.9%, final kilometer at 12%).
• Bilbao enforces major restrictions across Sabino Arana, Abandoibarra and Gran Vía from early morning, blocks general traffic on the Puente Euskalduna from 9:00, closes key tunnels before the start, and reroutes Bilbobus lines with tram service curtailed near Basurto.
• The N-634 faces time-window closures tied to the race passage, with Etxebarri and Galdakao implementing parking bans, local street shutdowns and bus service adjustments during the double ascent of El Vivero.
• Euskalmet forecasts a summerlike day near 30°C and largely dry conditions, as the stage also nods to Bilbao’s 90-year bond with La Vuelta and passes the hometown of 1957 winner Jesús Loroño.
