The powerpoint slides the dril posts towards the beginning of the thread do a very good job of interpreting the Canova style. When I used the Jack Daniels schedule leading up to Chicago, I found that I was struggling too much in his early phase 2 workouts, and too much variation in pace. For example (all in miles with the prescribed pace), 2E, 6M, 1T, 5M, 1T, 1M and 2E.
The important parts of Canova I have incorporated are: More frequent shorter workouts, which helps as I have a full time job. I tend to do about 5-6 workouts every 14 days; I think Daniels typically uses 2Q days per week. I haven't done a true special block yet, but I have done a few workouts on back to back days which are important. Fartleks are sometimes inserted between two harder workouts, which are a "B" workout, but still give the body time at Marathon pace. I think in the newest edition of Daniels, he recommends an easy range which for me was 6:15ish to 6:40, but I found that too fast to properly recover. Canova has a regeneration pace so I spend a lot more time at 7+ per mile. This helps me to run faster on workout days. Another thing I did for Houston was a full marathon at 2:24 which was about 97% of marathon pace in the specific period, 5 weeks prior. He recommends up to 40km but I thought doing an actual road race with support/water stations was beneficial.
The biggest difference for me is I spend a lot more time near marathon pace per week with Canova than I would with Daniels.
Also, I am assuming you are doing the basics as well: Eating well, sleeping 8+ hours a night, drinking alcohol minimally, good recovery drink, etc.
