Promote your recovery
Not only beginning runners benefit from walking, but also advanced runners benefit from a walking break from time to time. Walking is the best way to recover when you are training at top speed. It allows your body to replenish the store of creatine phosphate, which is used for short, explosive efforts. Although you may want to bend over with your hands on your knees to pant after a heavy exertion, it is better to keep moving. Active rest also contributes to the elimination of waste products that build up in your body during running. By not standing still after heavy exertion, but walking for a while, you stimulate this process.
So there is nothing to be ashamed of if you take a break from your run training by walking for a bit. In fact, by using walking in a targeted way, you can even use it to your advantage. Decide for yourself whether you would like to take a break with a walk during your run. If you feel that it takes you out of your rhythm, an easy jogging pace might work better for you – although your fitness level must allow for this.
