Thanks to everyone who offered up their input and expertise on this half marathon thing. And thanks to my brother Doug for pointing out the obvious that I am not Kenyan and therefore cannot run 10.5 - 11.5 miles/hour and that I clearly meant to say I hope to run 10.5 - 11.5 minute miles.
I'm feeling better. Today is my fifth day cigarette free and I don't feel as ill or temperamental. I'm feeling good.
