My quest for 6.7

My friend I understand what you are trying to do, I would do something a little higher.

Speed Session 1:
3x30
2x60 30m int limit

Speed Session 2:
4-5x20 blocks
x15 throws

Tempo 1:
6-8x100

Tempo 2: (I would only do one tempo session but if you must do two)
20min incline tread walk or pool session.

If you read the 10day taper thread TC talks about keeping longer runs into the program even when tapering.
