Abstract: A golf putting training device is described. In some implementations, the golf putting training device comprises a body having a first elongate portion and a second elongate portion that are joined by a center portion having an arcuate recess at a proximate end of the first elongate portion and the second elongate portion, with the first elongate portion and the second elongate portion forming a channel that has the arcuate recess at a proximate end and an opening at a distal end. The golf putting training device further comprises two guide pins, with each of the first elongate portion and the second elongate portion including a first mounting aperture pair disposed near a proximate end and a second mounting aperture pair disposed near a distal end, as well as one or more guide aperture pairs, each pair constructed to receive the two guide pins.
