This wasn't a breakaway rider inheriting a stage from a tired peloton. Buitrago put two separate gaps into Brenner on a climb averaging 7.2% with pitches to 21%, and both times Brenner clawed back before finding the sharper finish. That's the biggest win of his career, coming off a serious crash at the 2025 Giro d'Italia — a result built on refusing to accept the first two losses, not on raw climbing legs.
