Muscles recuperate best if given 48 hours to rest. This doesn't mean that you should not run more than two days in succession, but you should think seriously before running hard two days in succession. Regardless, Monday is always a day of rest for those in the Novice program, before or after the marathon. This is an increase of one mile from last week's Tuesday workout. I'm trying to get you back to a steady-state level, and one way to do it is to institute slight mileage increases.
Sudden increases offer a route to injury.
You might say that these midweek workouts are like a sandwich. Two relatively easy days on the outside with a relatively harder day on the inside. Don't stay out too late tonight. You still want to catch up on any sleep you might have lost during the hard weeks of training and, especially, before the marathon, when nervousness might have prevented you from sleeping deeply. Sleep loss is cumulative, and it's time to catch up.
