The ride of her career. The German national champion was the only rider outside Visma to make the four-up move that Ferrand-Prévot launched at Mons-en-Pévèle, and once Vas was dropped at 23 km she stood alone against the two Visma riders. Rather than wait to be controlled, she attacked the situation — strongest on the cobbles, dropping Vas, repeatedly forcing Ferrand-Prévot to chase back, and going again inside the final 5 km. On the velodrome she refused the cat-and-mouse, held her line in a side-by-side sprint against Vos and edged ahead at the line. A spring spent supporting Demi Vollering ended with Koch a Monument winner in her own right.

• 46 kmOnly non-Visma rider able to follow Ferrand-Prévot's move at Mons-en-Pévèle
• 23 kmRaised the pace on the cobbles to drop Blanka Vas — left alone against two Visma riders
• 18 kmAttacked repeatedly on the run to Carrefour de l'Arbre, briefly gapping Ferrand-Prévot
• 5 kmAttacked again before the velodrome — the trio reformed for the track
• 0.3 kmHeld her line in the velodrome sprint and beat Vos at the line

Added depth to FDJ's strong day with eighth from the front chase group, backing up Vollering's runner-up ride. A solid support result inside the top ten.

Koch was the engine of the winning move, driving a ferocious pace up the Muur that decimated the bunch and sprang Vollering and Niewiadoma clear. Having done the decisive teamwork, the German champion still finished fifth in the chase-group sprint, a standout domestique-plus performance.
