Go for it! Your story reads very much like mine, and I'm having great success with chi running. Like you, my previous running experiences were riddled with pain- shin splints, IT band-related issues, the whole shebang. The CR style has definitely lessened those issues for me. I've learned how to avoid shin splints, and how to listen to my body when it says, "hey, old cranky hip here- had enough!". (Many thanks to the wonderful TE ladies who have taught me how to manage and rehab that cranky hip!) 2 months into it, I've learned a lot, and it's been positive enough to keep me motivated to continue running and learning.

Start slow, buy good shoes, and really listen to your body. It will tell you if you're doing too much too soon (mine certainly does!). Good luck, and have fun!
