Proper Running Form and 10-20-30 Training

A short video on proper running form was recently posted on the web. I recommend this video to other runners and especially to heel-strikers that are converting to forefoot striking like me. I watched the video and wished it had come out 6 months ago because I had to learn to run on my forefeet by trial and error. One of the main themes of the video is becoming a forefoot striker is difficult and you have to approach it with caution. In my case, I had to start over from the beginning. I had originally injured the meniscus in my left knee because I was a heel-striker. I began a rehab running program beginning with short runs and added 10% mileage per week. But every time I approached 4 mile runs I would re-injure my knee. I decided I needed to become a forefoot striker to lower the shock to my knee. But I could only run on my forefeet for 10 meters initially. I began adding 25 meters per day until I reached 1 Km, then I added 50 meters a day until 3Km then 100 meters until 5 Km. This took a long time. At that point I began 10-20-30 training specifically to enhance my running form. 10-20-30 intervals really help improve my running form and now I can do my long run of 5 miles totally on my forefeet.
