Plan length chooser (conservative defaults)
-
16 weeks: best if you already have consistent running volume and you recover well.
-
20 weeks: best for most runners who want more gradual build and fewer risky spikes.
-
24 weeks: best if you’re returning from time off, building durability, or you want more room for cutbacks.
