We analyze the persistent current of non- interacting electrons in mesoscopic ballistic rings. We provide a semi-classical approach stressing the relevance of the underlying classical mechanics, and in particular of short periodic trajectories. In the limit of thin rings we recover previous theoretical results which we compare with recent measurements in the ballistic regime.
