Carbo Loading for the Austin Marathon

Hey Everyone!

I am running the Austin Marathon on Sunday and want to make sure I am fueled properly. 

I ate a full plate of fajitas, one marg with an extra salty rim for hydration, and approximately 3.5 baskets of chips tonight (which I believe equates to about 87 tortillas). I hope this is enough carbs for Sunday.

Any other tips and tricks prior to race day for proper fueling?

Thanks in advance,

Gene
