As mentioned last week, Good Form Running is a specific running practice which will improve your speed, and enjoyment of running. The second part to Good Form Running is the specifics of your foot strike. Your foot should contact the ground at mid-foot first. If you contact with your heel first you are putting a lot of force and jarring into your leg. Because of the high quality of running shoes that have so much cushion, runners often strike with their heal first and their legs suffer from the pounding. Try running barefoot and see what type of a foot strike you have then. When you run barefoot, you will automatically not strike on your heel, but run more on the mid-foot or balls of your feet because there is less jarring and pounding on your foot and leg. Spending some time running barefoot will help you find where that good foot strike position is. You can also march in place and see what part of your foot strikes first. As you run, striking with your mid-foot first you will run lighter and softer. This is not only good for your legs and knees, it is also good for your speed. Striking with your heel first is actually a braking motion. When you are trying to run fast, you do not want to put on the brake! You can wear whatever shoes you want, but find some time to practice running barefoot or in a minimalist shoe, either on grass, and indoor track or treadmill in order to develop a familiarity with and skill for striking on the mid-foot.
