Champ du Fou from Froidchapelle

At just 1.9km, Champ du Fou from Froidchapelle is short but deceptively intense — 57m of elevation packed into a brief, breathless effort. The average gradient of 3.1% disguises ramps of 6.3% — 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.
