Like the other Ardennes Classics, Flèche Wallonne is defined by its climbs and in particular – given the Belgian Classic is the only WorldTour race ending with a summit finish – its finish. Eleven ascents in total will pepper the 205.5km route of the 79th edition on Wednesday, culminating with a triple ascent of the ultra-steep Mur de Huy.
As Alasdair Fotheringham wrote in his preview of the race, the ascent of the Mur is one of the most dramatic and hallowed in the cycling calendar, with the focal point of the 1.3km climb the well-known 'S' bend mid-way up. This particular chicane, by far the hardest of the Mur, sees the road's gradient ramp up to a lung-bursting 24 per cent, and it is no coincidence that this is this point where numerous race-winning attacks have been launched in the past.
On the eve of the 2015 race, we've compiled a gallery of some of those past attacks and stars, dating back to Rik Verbrugghe's win in 2001.
