How to Lengthen Your Running Stride
If you're a seasoned runner looking to improve your performance, developing a longer stride can give you a competitive edge and a greater sense of ability. To lengthen your stride, you'll want to develop a "foot-strike" that's brief and powerful. Here's one drill to help you accomplish this.
Once a week, when you've completed about half of your run, take a break to practice a bounding stride. Spring from one foot to the other, pushing forcefully and quickly with each foot when it makes contact with the ground. As you spring from each push-off, focus on staying airborne for as long as possible. Do this several times, covering about 25 to 30 yards each time. After you've done several sets, finish your regular run with your regular stride.
