Week -7: 2/18
Week -6: 2/25
Week -5: 3/4
Week -4: 3/11
Week -3: 3/18
Week -2: 3/25
Week -1: 4/1
Race week: 4/8

In reality I have an extra day, because the marathon is on Monday, but it is easier to have a Monday-Sunday schedule, and the timing of the long runs and workouts works much better this way for my work schedule.

Tune-up races:
3/2, 3/16, 3/30

Probably no chance of racing in March 2-3: the map of the US has big hole for that weekend for races between 8K and 15K!
