Running speed comes from both the length and rate of your stride. If you want to increase your speed without injury, you will need to train your stride for optimal performance. To do so, you will need to prepare with some general exercises before you start to widen your stride and increase your stride rate.
Another option would be to increase cadence by distance. For example, run every third mile at a higher cadence. The key is to continue to make the length of time/distance longer until your whole run is performed at a higher cadence.
