I Was Runnin'! (said in my best Forest Gump accent impersonation)

I need to make this declaration now, so I can be held accountable by all my favorite blog readers (and other running gurus...especially Amy, Angela, and Andrea who I know have run full marathons before, plus so many more of you who are amazingly committed to running/triathaloning). This year I am planning on running a marathon. There. It is said. Yipes! The Seattle Marathon is at the end of November, and my sis-in-law, Ashley, is planning on running that and I would love to do that one with her, but I don't want to do it without Adam cheering me on (let's face it, this may be a one-time shot, so I want to make sure he witnesses it!) so if he can't make it out there then I will have to find another one out here around that same time. The America The Beautiful Half-Marathon is on Labor Day, so I am going to do that, and see what I can find sometime in late November/early December here for the Big Kahuna--the full marathon. Eek! I can't believe I am actually going to commit! I am up to 7 miles for my weekly long run, so I think I can make it. I am just kind of freaked out. Is a body really meant to run that far? Didn't Phidippides die after he delivered the news of the Athenian victory at Marathon?
