A prolong-tracked elliptical exercise machine has a base, two poles, two pedal assemblies and a wheel assembly. The pedal assemblies are mounted oppositely beside the base and each pedal assembly has a linking bar, a rail and a pedal. The linking bar is pivotally mounted between the corresponding pole and the wheel assembly. The rail is mounted securely on the linking bar. The pedal is mounted slidably on the rail and is synchronized to and moved along the rail by a driving assembly driven by movement of the wheel assembly. Accordingly, since pedals move relative to the rail, a distance of pedal movement is increased to provide greater exercise advantages at low cost.
