sensitive nerves come out in last days before the run!

I begin to wonder if all of these pains I'm starting to feel are merely phantom pains i'm imagining out of heightened sensitivity to my body. Knowing the run is coming on sunday I'm much more aware of every pull and ache I feel in my muscles, a light throb of my head, anything. Maybe I'm sore but I think I'm just nervous these baby pains will under the strain turn into significant problems. regardless I'm stoked to get my gear on and be surrounded by equally as adrenaline-pumped runners! to the start line!
