La Tombelle via Aulnoit

At just 1km, La Tombelle via Aulnoit is short but deceptively intense — 33m of elevation packed into a brief, breathless effort. The average gradient of 3.4% disguises ramps of 6.9% — 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.
