What you're going thru is so common I have a name for it ("taperitis"). Your week reads like it's been practically lifted from an old log of mine befoe I race where I ran pretty well.
I typically feel very lousy until 2-3 days before. Sometimes I dontl even feel good the day of, but yourl;e training so you can run when you feel bad, b/c anyone can run when they feel good.
I do a really really sharp taper, 3 weeks. My last week is maybe 35 miles.
Some differences....my last track practice (Wed or Thur for a Monday race) is 8 x 300 at mile-3k pace, with a 2:00 rest (full rest). Enough work to feel like I am working your muscles again, not enough to make me tired. And it's so much faster than marathon pace b/c I don't want to teach myself a stride rhythm that might feel kinda sorta like natural mthn pace on race day but be suicidally faster than it shd be.
For Monday race, I do maybe 25:00 of jogging on Friday. on Saturday (even if it's travel day) I do a "warmup" -- sweats on, jog 10-15 minutes near home until I break a sweat, and then stop. Day before the marathon off.
