Block length.

Block length is the number of weeks the AI spends building toward your peak before the program restarts a new cycle. Set it in Settings → Training inputs → Program shape under your stream’s preferences card.

Allowed ranges depend on the stream:

Hybrid, Strength, Hypertrophy — 8 / 12 / 16 weeks. 12 is the canonical default.
Half marathon — 10 / 12 / 14 / 16 weeks. 12 is the canonical default.
Full marathon — 16 / 18 / 20 weeks.
Hyrox — 12 / 14 / 16 weeks.

Pick 8 (or the shortest available) for a fast restart or a near-term goal; pick 16+ for a longer build with more time to accumulate volume before sharpening. Changing block length re- phases the upcoming weeks on the next rebuild. The current week stays as prescribed.
