Race guide

La Flèche Wallonne

La Flèche Wallonne is a Belgian one-day WorldTour race held each April in Wallonia. The route loops through the Ardennes before finishing atop the Mur de Huy, a 1.3-kilometer wall with gradients reaching 26 percent that has defined the race since 1983.

Eddy Merckx won the first edition in 1936. The Mur de Huy finish was introduced in 1983 and has been the race's signature ever since.

Why this race matters

Few races compress their drama into such a narrow window. The Mur de Huy appears three times during the race, but only the final ascent matters, and by then positioning, timing, and raw climbing power converge into roughly three minutes of racing that settle everything. The climb is steep enough to eliminate sprinters, short enough to reward explosive accelerations, and visible enough that you can watch the entire finale unfold in a single camera shot. It rewards a specific type of rider: punchy climbers who can survive a hard day in the Ardennes and still produce a sustained effort on gradients that feel more like a ramp than a road.

How this race is usually won

The race covers roughly 200 kilometers through the hills of Wallonia, with the Mur de Huy climbed three times in the final 60 kilometers. The first two ascents thin the field and set up positioning battles, but the race is won on the third. The Mur averages 9.6 percent over 1.3 kilometers, but the gradient is uneven: it eases slightly at the base, steepens through the middle section where many attacks are launched, and pitches up again near the line. Riders who go too early fade visibly in the final 200 meters. Those who wait too long run out of road. The ideal move comes with 400 to 500 meters remaining, though the timing shifts depending on wind, fatigue, and who else is left in the group. The climb is narrow, which makes positioning in the final kilometers critical. Crashes and poor placement on the approach have ended more contenders' chances than the gradient itself.
