Rue de Trez via Rue Haute Froidmont

At just 0.9km, Rue de Trez via Rue Haute Froidmont is short but deceptively intense — 47m of elevation packed into a brief, breathless effort. The average gradient of 5.3% disguises ramps of 12.9% — 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.
