"Does he talk about his stride? I read about chi running somewhere on the forum, but cant find the post anymore that described the stance and form of the stride."
Take a look at www.posetech.com the running method is so similar that some of the pose supporters think the chi running guy stole it (how can you steal a style of running?). Anyway the pose website has a lot of good info for free and a decent message board.
The basics of the running style are:
-cadence of atleast 180 contact per minute
-land on the forefoot contacting the ground directly under the hip.
-at the time of contact the leg should be slightly bent to absorb shock. The leg is never completely straightened.
-try to contact as quietly and softly as possible
-use the hamstring to explosively remove the foot from the ground as soon as contact is made, bring the heel directly towards the butt.
-keep the back and neck straight eyes looking at a point ~100ft ahead
-keep the shoulders relaxed and down
-arms should be bent at 90 degrees and swing pretty much straight ahead and straight back (swinging arms across the front of your body causes your trunk to twist, this is a bad thing)
-forward lean. Keeping your back and neck straight lean forward very slightly. You are not bending at the waist but sort of failing forward with the sternum leading. The further forward you lean the faster you will run. For slow running there is almost no noticable lean at all.
The last thing is footwear. The forefoot landing is easier to achieve with a shoe that has little or no heal lift. Your aren't landing on the heal so you won't need the extra padding there anyway.
I don't think I missed anything but you'll find better and more detailed explainations at the website I listed. I think they have even added video to help demonstrate.
