1. A golf club head comprising: a face having a striking surface configured for striking a ball, a body connected to the face and extending rearwardly from the face, the body having a crown, a sole, a front, a rear opposite the front, a heel, a toe, and a hosel located adjacent the heel, wherein the body and the face combine to define an internal cavity, and wherein the golf club head comprises an exterior surface and an interior surface, wherein the golf club head has a volume of at least 400 cubic centimeters, an elongated channel extending across a portion of the sole, wherein the elongated channel is recessed from adjacent surfaces of the sole, and a plurality of internal ribs, at least one internal rib of the plurality of internal ribs connected to an internal portion of the sole and to an internal portion of the elongated channel, wherein the elongated channel has a maximum width and a maximum depth of recession along a length of the elongated channel, wherein the elongated channel comprises a wall thickness, the maximum width is defined in a front to rear direction and the maximum depth of recession is defined from adjacent surfaces of the sole, wherein both the maximum width and the maximum depth is defined at a vertical plane passing through a face center, wherein a ratio of the maximum width to the maximum depth is approximately 3.5:1 to 4.5:1, wherein the elongated channel comprises a center portion extending toward the heel and the toe from the vertical plane passing through the face center, wherein the center portion is generally symmetrical with respect to a vertical plane passing through a geometric centerline for the sole, wherein a maximum width of the center portion varies no more than +/−10%, wherein a midpoint of the center portion is coincident with the vertical plane passing through the geometric centerline for the sole, and wherein the vertical plane passing through the face center is aligned with the vertical plane passing through the geometric centerline for the sole, a heel portion extending from a heel end of the center portion toward the heel, and a toe portion extending from a toe end of the center portion toward the toe, wherein the elongated channel has a boundary that is defined by a front edge and a rear edge that extend between a first end and a second end of the elongated channel, and the front edge and the rear edge at the heel portion and the toe portion are angled away from each other such that an elongated channel width at the heel and toe portion gradually increase toward the heel and the toe respectively, and further wherein a depth of the heel portion and the toe portion of the elongated channel increases from the center portion toward the heel and the toe, respectively, wherein the front edge of the elongated channel is rearwardly offset from the striking surface of the face a rearward spacing distance, wherein the rearward spacing distance of the front edge of the elongated channel varies in a range from 8.00 mm to 9.35 mm, wherein at least one internal rib of the plurality of internal ribs comprises an internal corner rib adjacent the hosel connected to an interior side of the sole, an interior side of the crown, and an interior portion of the rear edge of the elongated channel.
