Heid du Pouhon via Rue Grand Plain

At just 1.4km, Heid du Pouhon via Rue Grand Plain is short but deceptively intense — 75m of elevation packed into a brief, breathless effort. The average gradient of 5.3% disguises ramps of 11.8% — the kind of gradient that turns plans into prayers. It's over before the legs know what happened — a short, explosive effort where momentum is everything. Located in Wallonia, Belgium.
