A guide carriage for an elongated guide rail includes a main body, an end cap, and at least one row of rolling bodies accommodated in a continuous bypass channel. The end cap bears indirectly against a longitudinal end face of the main body and has a fastening bore through which a fastening screw passes. The fastening screw is screwed into the main body. The continuous bypass channel has a supporting portion and a return channel that are connected via a curved bypass channel that is arranged in the end cap. A lubricant flow path is arranged in the end cap and extends from a lubrication port to the row of rolling bodies. A first cavity is arranged between the fastening bore and the fastening screw. The first cavity forms a component of the lubricant flow path.
