Garbage in/Garbage out

So... I was supposed to run for like 2 and a half or 3 hours today. But yesterday evening, I ate a shiz load of Carls Jr. Im talking like 2000 calories big. Needless to say, I did not run well today. I ran at the buffalo trail for like 3 and a half miles but just wasnt feeling it, so I drove to bush park and ran one lap. I just couldnt get it going today. Also, I donated blood yesterday, so I am sort of using that as an excuse as well. But mostly I am pretty worthless. I really need to pay closer attention to my diet and how it affects me in my running. Buh-Bye.
