La Flèche Wallonne and La Flèche Wallonne Femmes are Classics unique among the calendar of WorldTour races, culminating with the leg-breakingly steep climb, the 1.3km Mur de Huy which hits 22% in places as it winds up beyond the Walloon town of Huy.
The race is somewhat unique for a one-day Classic in that all the deciding action is confined to the final 1.3km of the race up the double-digit gradients of the 'wall'. As such, it suits puncheurs and pure climbs with explosivity in their legs.
