Here is the theory. Lean forward until you start to fall. Put one foot out to catch yourself. Note where your foot lands. This is where your foot needs to land to stop a fall. You will feel a significant jolt. You have successfully sucked up all the energy of your fall and stopped yourself. You put on the brakes. Now try this again, but place your foot short of where you did the first time. You shouldn't fall, but you will keep moving forward and will need to take another step to stop the fall. Now you have stopped yourself from falling over two steps which is less jolting. Now try again and place the second step short of where you would need to place it to stop, then the third, then fourth. Now you are running. If you want to go faster, shorten your stride and focus on turning your feet over as quickly as you can. If you want to slow down or stop, lengthen your stride and absorb your forward energy. You could overcome the braking action of a long stride by pushing off hard with your back foot but this is not as efficient and harder on the joints. That's the theory. The way to find out if it works for you is to experiment. For me, as soon as I understood this, running became a lot easier. If it works for you, be sure not to overdo it at first.
