Young American Brandon McNulty won no medal but perhaps an enhanced reputation after hopping into breakaways up and down the slopes of Mount Fuji, literally.
The pro teammate of Tour de France champion Tadej Pogacar broke away with his colleague and Canadian Michael Woods on a fearsome climb late in the race, only to be hauled back by a dwindling band of elite riders.

Caparaz stayed out in front and won a solo breakaway. McNulty fell back and was just nosed out in a bunch sprint for the silver and bronze.
