A stroller track system is used to facilitate the transporting of a stroller up and down stairs. The stroller track system includes a left tread assembly and a right tread assembly. The left tread assembly and the right tread assembly are used to engage multiple stairs while traversing a set of stairs. This allows the stroller to glide smoothly up or down the stairs. The left tread assembly and the right tread assembly each include a first track and a first stroller-attaching mount. The first track has a greater surface area than a normal wheel, allowing the first track to span a larger section of a staircase. The first stroller-attaching mount is used to attach the first track to a stroller. In alternative versions of the stroller track system, the left tread assembly and the right tread assembly may include additional tracks to further stabilize the stroller.
