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.
1 Mid-distance runners may want to improve both stride length and rate. They will need to focus on glute, hamstring, hip, and core exercises.  Endurance runners may want a shorter stride length and a faster stride rate. They will want to work on core, glutes, and hamstrings.
