Teigyr,

The main difference between "power running" and "chi running" is that you use your core to chi run and purposefully relax the rest of your body. Instead of landing on your heel, you land mid-foot. The way that you move forward when you run is to engage your core and then lean forward. The more you lean, the faster you run. The theory behind it is that you let gravity do most of the work for you. Also, you are highly encouraged to have a very high cadence when you run - 90 beats per minute, counting when one foot hits the ground.

This is an over-simplified explanation of chi running, but these are the main focuses of what chi running is all about. If you go over to the chi running site - www.chirunning.com - and read the library articles, you will get a much better feeling for what chi running is all about. They also have a discussion board that is very helpful too. Their two main blog moderators, named Jacquie and Laura, are very, very knowledgeable and helpful.

Hope this helps a little bit,

Lynette
