Here is the Q and A:
Q: What is Running Cadence?
A: Running cadence is the number of times either your left or right foot hits the ground in one minute. Concentrating on improving your running cadence can make you a faster runner and help you exert less energy while gaining the same amount of ground. Studies have shown that the world's fastest long-distance runners have a higher cadence than the average runner, between 85 to 95 steps per minute.
Q: Is that true? Why is it important?
