Frustrated

I am doing the NYC Marathon this weekend. I didn't envision my NYC Marathon attempt to be as it will be. I got sick Oct 16, missed my long run that weekend, ended up struggling through the week at work, was diagnosed with strep throat on Oct 23, missed my last long run, tried to run long on Tuesday and felt like crap so I bagged my long runs for training. (Wow, a long run-on sentence.) I have managed to finally feel good enough to run a fairly difficult 6 miles on Sunday at the Squirrely Six miler but I am really slow. I am finally feeling better though. I was doing well up until Oct 16 when this cold just hammered me. I was lucky to get off of my couch and go to work most of those days. I felt like it was all going as planed and I would be where I was supposed to be. I guess sh$# happens though. So, I am going into NYC grossly undertrained (having only gotten up to 13.5 miles running - 2 hrs 39 min as a total long run) and slightly worried. I have walked a good portion of a marathon before, after 127.5 miles - at least that isn't the case this time. I just have to enjoy it for what it is worth and hope for the best!!! I just hope the best is under 5 hrs 30 min! NYC here I come!
