If you have an injury from jogging or running or are just looking for a new way to enjoy your sport, you might want to try ChiRunning. Created by San Francisco-based coach and runner Danny dryer, who for 30-plus years has raced every distance from a 10k to 100 miles, this combo medls the concentration and smooth, flowing movement of tai Chi with the power and energy of running. By focusing on posture, form and efficient movement, ChiRunning relaxes tired, stressed joints and muscles and provides a gentler, more meditative experience with less potential for injury or re-injury. The Introduction to ChiRunning CD or audiotape and booklet is $20 plus $3.50 shipping and handling form ChiRunning.com; a videotape will be available later this year.
