Alright, here are some quick, pre-sleep thoughts:
1) You got way too much MaxV going on here. You're using MaxV for approximately 5 months. No, no, no. I think you should do 2-3 months of Acc. Dev. (not just straight sprints….hills, sleds, stairs are all acc. dev.) and towards the end of that time start including MaxV.
2) You not only use too much MaxV, but you never vear away from it. Towards the beginning of your main competitions I'd start working on short speed to incorporate both MaxV and Acc. Dev. in the same workout. Plus it's a good way to taper off since volume will be lower than a MaxV or Acc. Dev. workout. You're doing less reps, but at higher intensity, so it's like getting more bang for your buck.
3) I don't see any need for a track runner to do leg depletion work at all. Between lactic work and weightroom work your leg depletion work should be taken care of. Leave depletion leg exercises for football players.
4) I think you should always include straight lifting. Who says it has to be "heavy" per se (>80/85%). What about just lifting in the 75-80% range? Not "heavy" but still better than straight circuit training the whole time. Gotta include SOME of it.
5) Your SE looks alright in the way you've got it set up for the most part, except one thing I'd change would be to start off with full recovery on SE2 and decrease rest intervals as the reps start getting shorter as fitness should be high and you should be able to do SE1 and SE with much shorter rests. If you need 15-20min to do a 150m towards the "beef" of your season, then you're doing something wrong. You're doing lots of Lactic work early, which I favor, but then start going into some Lactic power work and then into SE (part lactic power, part lactic tolerance work).
I think that's it. Like I said, I'm tired and I gotta get to bed. I'll proly post more later, but lemme hear some feedback so far.
