voie à plusieurs longueurs de corde

OBS: Proposition faite à partir de la source : Pratique de l'escalade de Jean-Claude Salomon et Claude Vigier, qui utilise la locution «voie longue supérieure à deux longueurs de corde».

CONT: Climbing a multi-pitch route is much more complex than climbing a shorter rock, partly because it requires the climber's serious commitment.
OBS: A multipitch route at higher elevations or in a remote region [requires] mountaineering and winter travel skills.
