Danny and Katherine Dreyer are the co-authors of three of the most valuable books ever on human bipedal locomotion: Chi Running, Chi Walking, and Chi Marathon. The promise of their methodology is that you can walk or run a lot farther and faster, without pain or injury. I can personally testify to its effectiveness, AND to my own ability to learn something great and totally forget about it for, like, a decade and a half. I met Katherine and Danny at their home in Asheville, where they regaled me (and now you) with tales of ultra-running and pain, and discovering how to apply the principles of Tai Chi to running, and starting a business and movement.
