The Vuelta is won in the mountains. Expect multiple summit finishes, often on gradients that exceed ten percent for extended stretches, and relatively few flat stages compared to the other Grand Tours. Time trials matter, but they rarely decide the overall unless the climbing has already separated the field. The race often begins outside Spain with a short opening loop, then moves south or west before turning toward the northern mountains in the final week. Crosswinds occasionally split stages in Castile or along the coast, but the defining selections happen on steep climbs in the Asturias, the Pyrenees, or Andalusian ranges like the Sierra Nevada. The general classification is usually settled in the third week, when cumulative fatigue meets the hardest climbing. Stage hunters have opportunities throughout, especially on medium-mountain stages that are too hard for sprinters but not decisive enough for GC teams to control tightly.
