Runners - Stride Right
Finding the best length for your running stride may protect you from injury as well as allow you to run longer and faster. Exercise physiologist and running coach Jack Daniels, PhD, advises runners to find their optimal stride by aiming for 180 steps per minute.
Without focusing on form, try counting the steps on one leg for one minute and see how close you san come to 90. The optimal rate should feel like you are running “over the ground, not into it.”
