Every since High School, I have followed most workouts with 6-7 striders (roughly 100m in length). I do it to improve my running form and to develop my stride length. Besides, as much as they may suck after a hot or difficult workout, they do a great job of loosening me up.
I recently found a similar workout that, instead of increasing stride range, increases stride rate.
The Workout: Down Hill Strides
Ideally you would do these going down a grassy slope. The point is to control your acceleration, taking short, quick steps. Remember, you don’t want to over stride. Over striding puts increased impact on you knees, esp. going down hill.
As in regular strides, jog back to the top of the incline and repeat. Do no more than 8.
