I don’t know if the earlier you start, the better you will be by March is really true, because the earlier you start, the more chances you have to peak too soon.
As for the setup, instead of adding weird stages like you did, you could just do this:
AA: 4 weeks
GPP: 8 weeks
SPP: 8 weeks
Pre-Comp: 8 weeks
Competition
Here is the thought process:
AA - No speed training, plyos or anything. Just weightlifting, hills, grass runs and anything non-track related. Just get your body in shape and ready to go for the rigors of training to come. Stay off the track as much as possible and try to do tempo runs on grass. The weightlifting is also in an AA type format.
GPP - Start introducing Acc. Dev. and plyos. Go 1 day a week on Acc. Dev. while maybe doing Int. Tempo one day and Hills on the third hard day while Ext. Tempo is everyday between. By the end of this phase you should be able to roll and start doing speed work. Also, if you want, make your weightlifting hypertrophy-based doing two 3-1 cycles of it.
SPP - Lock and load and get ready to roll. Acc. Dev. turns into speed work (reps of 40-60m) and you can start introducing speed endurance 1x a week or every other week if you choose. I personally am doing split runs during this phase as a speed/speed endurance setup workout (confusing?). Workouts like this:
250/30sec./3x60m
200/30sec./2x60m
150/30sec./60m
Kitkat uses these and in the HSI…10x600 thread he explains all about them on the last two pages. These are some definite gut-work workouts and will pay great dividends to get you ready for speed endurance and Special I. Ext. Tempo between everyday and by the end of this phase you will have reached your tempo “peak” and from now on tempo volumes will go down so efforts can be focused on CNS work.
Pre-Comp. - Now you start doing MaxV (60-80m reps) along with speed workouts all together with speed endurance/special I. So Monday and Friday you could do speed/MaxV and Wednesday you could do speed endurance/special I depending on your choice. Ext. Tempo is going down now to make room for real workouts.
Then competition you obviously know about.
The split runs…the first rep could be run at about 85-90% max effort with the supplementary runs at full speed w/ walk back rest.
If you want you could probably repeat a meso (3-1) of GPP or SPP depending on you. Make sure you do tests and see how you are progressing so you can make changes.
That is my 2cents for now. Does anyone else want to add anything to or bash my ideas?
