Les Grands Trieux from Carnières

At just 1.3km, Les Grands Trieux from Carnières is short but deceptively intense — 68m of elevation packed into a brief, breathless effort. The average gradient of 5.3% disguises ramps of 12.8% — 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.
