The invention relates to a gliding board including a structural beam defining a longitudinal direction and having a gliding surface bordered on each side with a lateral running edge, each running edge having an edge body and an anchoring blade, the anchoring blades of the two running edges being oriented opposite one another. An inextensible connecting element locally connects the anchoring blades, at least along a portion at least of the length of the beam, and the connecting element is oriented in the extension of each of the blades.
