What 16 weeks can doReal physiological change. Long runs climb from the mid-40s towards 75+ minutes, strength progresses across three blocks, and the specific phase lands on a base that can hold it.
What 16 weeks cannot doStop you drifting. Eight weeks in, the race feels abstract and sessions get skipped. Three deloads and front-loaded variety are there for exactly that.

How does this differ from the 8-week plan?+
It is the 8-week plan with room to breathe: a longer base before the specific work, 3 deload weeks, and space for race rehearsals far enough apart to act on. This length is generated from the same phase engine at four sessions a week. The 8-week plan is the hand-written flagship.
