Hey Runner---I don't think you should have too much trouble with a ten miler, I would suggest a high fat breakfast the day of the run, that should hold you and get the fat burning too. I have run a lot of marathons in the past, and it seems that no matter what I eat, I start to run out of energy before the finish, you just have to make up your mind that you will cross the line, and you will. The last marathon I ran, I placed 9th and had torn the ligaments in my knee about 4 miles from the finish line, I finished because I told myself I would. You will do ok if you have been putting the right amount of work on the road. Good luck with your run---Taku John
