A jogging stroller has a collapsible frame comprising two side rails having rear ends pivotably coupled to handle, two front wheel sub-frames having rear ends pivotably coupled to front ends of side rails and front ends rotatably coupled to a front wheel, two rear wheel sub-frames having front ends pivotably coupled to front ends of side rails and rear ends rotatably coupled to rear wheels, two base rails having front ends pivotably coupled to front wheel sub-frames and rear ends pivotably coupled to handle, and a seat assembly extended upwardly from base rails and including a front seat and a rear seat in a longitudinally aligned relationship to the front seat. In collapsing, front wheel sub-frames and rear wheel sub-frames are pivoted toward side rails, handle is pivoted toward side rails, and base rails are moved to abut on side rails as the pivoting of front wheel sub-frames and handle, resulting in a reduction of storage space.
