As if I needed something else to worry about, I discovered today that I need to increase my cadence. According to the Garmin watch I wore during my workout on the treadmill, my running cadence is 77 steps per minute. Since I had no idea what that meant, I looked it up. It turns out that I should be taking more steps. Elite runners take over 180 steps per minute! A slow cadence uses more energy than a fast one and might increase the risk of injury.
So now what do I do? Frankly, I've been too busy just gasping for breath during my runs to worry about how many times per minute my feet strike the ground. Maybe ignorance really is bliss.
