Sorry it's been a while since I've really had time to read a lot of the posts on here. I think the set up looks fine. On the days that have "29th street hills." Those should be hills that are around 200 meters long.
I don't know what no doing Int. Tempo has to do with a better peak. However when they get down to 200's at @ +:03-:02, :01 that, that will be some Int. Tempo, just with a very short rest (2:00). They should be strong enough that they can do that kind of workout very easily. They will also be able to do at work of 4x200m at :23 w/ 2:00 rest very, very easily.
There are testing dates in the program. One around Thanksgiving and two before X-Mas break. Typically you can have them run a 200, 300, or 350 at thanksgiving then 200 and 400 at the two trials before X-Mas.
Prior to the workout beginning in October. From June to October just lift and THAT'S ALL. If you are going to have the kids workout during the summer with a program I think it may be a bad idea. Because most kids do not run until track practice starts in February. If you have them run from June to June they'll burn out, I've seen it happen.
All of the runners are split into groups for the workouts. Ex. Group 1 Rock, Bockman, Toshner. Group 2 Svestika, Olson, Marcinek, Deterville. You divide them according to what they have run. YOu can adjust that as your runners run faster. When you run the 450's, 500's, 600's etc. Have them in their groups so that they are essentially running the same pace and not racing. You don't want to have your athlete that runs :52 in the quarter running workouts with someone who runs :47. He'll burn out from trying to race.
Hope that explains it for you. Let me know of any other questions and I'll answer much quicker.
