I’d be interested in seeing how you are progressing the individual elements a bit as one can say “accel” “long accel” “ext. tempo” and the like and mean very different things from a volume/density/progression standpoint.
In your SPP1 base template, I’m a bit curious about the set-up because if you put the weeks together rather than just look at one week, you see that you have Max V days in 3 out of 5 consecutive days, which seems a bit excessive IMO for a 400m runner. Quite excessive for anyone actually, but especially a 400m sprinter.
The third group is a sample SPP, and there are only two accel/speed days. The second group is a late GPP/early SPP, and there are three speed days, but the volume on any given day would be less than if we were doing only two speed days. When we’re doing three speed days, the accels are short, the max v work is limited to one of the days, and the other day is a speed/speed endurance day. Depending on the volume, we may not do any accel work on the speed/speed endurance day.
By the time we start doing any split runs, intensive tempo, or special endurance, there are only two speed days, with one being more a max v focus and the other being a speed/speed endurance focus.
My point in posting was just to illustrate how one ‘concurrent’ or ‘ends-to-the-middle’ set up might work. If someone is doing strictly S-L, I would think they probably need to already have a strong endurance background such as soccer, cross country, or previous 800m experience. I don’t really like the L-S setup, due to to influences of CF and kitkat, who both stress the need to train speed from day one. And from my experience working with an athlete who did not play soccer, run cross country, and has never raced anything 800m or longer, we need the whole year to work on aerobic capacity and special endurance. So my post was to stimulate discussion with Mike, who stated above that he didn’t like ends-to-the-middle. I wanted to see how he would address speed throughout training, as well as how he would address aerobic capacity and special endurance.
