Benoit Cosnefroy (Decathlon AG2R La Mondiale) continued his stunning run of results for 2024, powering to the victory in the prologue of the Boucles de la Mayenne.
Already a winner of the Tour des Alpes-Maritimes, Paris-Camembert, Brabantse Pijl, the GP de Plumelec-Morbihan and Tour du Finistère, Cosnefroy bested Ivo Oliveira (UAE Team Emirates) by a single second in the 5.4km individual time trial.
Sam Watson (Groupama-FDJ) was third at three seconds.
The four stage race continues on Friday with a 167.5km stage from Renault Saint-Berthevin to Ernée on a lumpy parcours that should suit Cosnefroy as well.
