“The most common mistake runners make is overstriding: taking slow, big steps, reaching far forward with the lead foot and landing on the heel. This means more time on the ground, which means the vulnerable heel hits the ground with more force on landing, creating more impact on the joints. Training at a stride rate of 85 to 90 is the quickest way to correct this problem. Short, light, quick steps will minimize impact force and keep you running longer, safer. It also will make you a more efficient runner.”
