Rue des Ecoles from Haillot

At just 0.6km, Rue des Ecoles from Haillot is short but deceptively intense — 36m of elevation packed into a brief, breathless effort. The average gradient of 6.5% disguises ramps of 13.2% — 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.
