400m S-L questions

Sorry I meant Edmonton.

Does the 400m short-to-long start out with the focus on acquiring as much top speed as possible early in the first special prep. training cycle (say doing lots of 50-60m sprints; flying runs and acceleration work) so that by special prep phase two the athlete would start to lengthen them runs out (say to reps of 80m and 100m moving eventually through to reps of 120-150 come the middle of this phase, ending with runs of 200, 250 and 300 at the end of a 10-12 week phase two)?

As far as SE progression day 1 has 4 x 60m with 2.5m rest and the last session in week 12 is 300+100 30 sec rec with plenty of variety in between.
