400m S-L questions

[Charlie_Francis]

@John

Charlie,
in your 400 S-L template for the SE you spend the first 10 workouts not running past 80m at a time then in week 6 you go session 1 to 100m then session 2 is a split run with 200m as the first part and then the 2nd session of week 7 is out to 300m. While the number of split reps drops and the total volume is similar that seems a comparatively fast progression. Why is that and not more in the 120-150- 180 range?

Anything is possible but remember that you adjust indoor to outdoor here and must be ready on time and the adjustment is not as dramatic as it seems when you consider the totality of the split runs.
