You'll be great Arielmoon!
I did a gel an hour for the first 4 hours. Then I was at the lunch stop and had a banana and PB&J. Each hour after that I snacked on cookies and crackers w/ pb. I was surprised that was all I needed to get through (also used the cytomax--24 oz bottle each hour). However, I carried an extra clif bar in my jersey in case I needed it.
