The
Alderney Race is a strait that runs between
Alderney and
Cap de la Hague, a cape at the northwestern tip of the
Cotentin peninsula in
Normandy. A strong current runs through the race north of the Passage de la Déroute, a treacherous passage separating the Cotentin from the
Channel Islands. The current is intermittent, varying with the tide, and can run up to about twelve knots during equinoctial tides. The French call it
Raz Blanchard. In
Norman French it is called
L'Raz.
