Hurting My Left Knee

I will run for the marathon in Shimanto Town of the Kochi Prefecture on April 5th this year. My left knee has been bothered me a lot lately. I have had major set back for my running practice. I have talked to a lot of people about this, and a trainer at a gym told me that I put too much weight on my left knee. He said my balance is not good. When I stand straight, my upper body obviously leanes toward to the left side. I need to fix my balance ASAP. Runner's World magazine and its website have helped me through this problem. I have learned I need to do a lot of hard work besides running if I want to run better. In order to do that, I need to manage my time more efficiently.
