I have never been more disappointed at myself. I could not finish my 18 miles :( I ran 13 miles in 3 hours. If I keep that pace, that's a pathetic 6 hours for the whole marathon. I am so ashamed of myself right now. Urgh. After the 7th mile, my toes started to hurt really bad. It was only after coming home that I realized that I hadn't cut my toe nails in a while and that's why it hurt so bad. Next week is 14 miles but the week after is 20 miles. I HAVE to finish the 20 miles no matter what. That time I'll make sure my toe nails are clipped, my shoe laces are tied tight, and my foot isn't hurting anymore.
