Countdown to Boston-7 Days to go

A week from now, I will be in Boston. As I write this, it's 10:15 a.m. pst which means that if I am running well, I will be near the finish of the race exactly a week from now. For the past few days, I have been feeling the usual pre race jitters/regrets. Did I do enough long runs, enough speed work, enough racing? By now of course, its too late. For this race, I've tried a pretty aggressive taper, halving my milage, but doing some fast tempo runs and pick ups when I do run. My weight hasn't gone up. I'm happy about that. Today, I'm doing a 7.5 run with some pick ups.
