Rue de Terstraeten via camping Kon-Tiki

At just 1.7km, Rue de Terstraeten via camping Kon-Tiki is short but deceptively intense — 77m of elevation packed into a brief, breathless effort. The average gradient of 4.6% disguises ramps of 11.6% — 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.
