When to start

A build for this distance usually runs 10 to 16 weeks. Counted back from race day, that puts the start somewhere between November 23, 2026 and January 4, 2027.

These ranges are working conventions, not a research finding — no trial has compared plan lengths against each other. What matters more is that the plan was built for the weeks you actually have, rather than shrunk down from a longer one.
