La Grande Bruyère from Rixensart

At just 0.9km, La Grande Bruyère from Rixensart is short but deceptively intense — 47m of elevation packed into a brief, breathless effort. The average gradient of 5.2% disguises ramps of 11.8% — 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.
