As I understand it, you should be on week 6 of the plan and are currently on week 3. Without knowing your background, why you were in a rough shape (Illness, injury, etc ) it would be difficult to give full safe advice. That said….
Here is my advice from a runners perspective….
The plans should be on a 3 week cycle. 2 build-1 taper. A possible plan (provided you have the background to do it safely) is to delete a build week until you reach your correct week. It would look like
Cal. Plan
Week. Week
6. 4
7. 6
8. 7
9. 9
If you are newer, I would most likely suggest investing in a custom plan to avoid any injuries.
