Technique will matter more. The book Chi Running is a great start. It's an unfortunate title but the content is great. I recommended it to a friend years ago that had broken his back and was unable to complete the running part to enter the police academy. I thought he was going to burst into tears when he thanked me after being able to complete a lap on the local track. I've heard Pose Running is another good system. Good luck!!
