Marathon update

So I know that a marathon is going to be super hard. Well, Yesterday my dad and I did 14 miles. Ran part, walked part, were boggled. It was very very hard. I have never been doing something so strenous for so long that my muscles are feeling sore from the prior two hours and I AM STILL ACTUALLY EXERTING MYSELF! It took us four hours on the dot and when we were done we were spent! So in the actual marathon it will be like doing that, and then turning around and doing it again. Hmmm.
