When to start
At this distance, a build usually runs 12 to 20 weeks. The 2027 date is not published, so counting back from October puts the start around May 24, 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.

The big marathons: what each one actually demands

Questions
What is the date of Marine Corps Marathon in 2027?
The organizer has not published the 2027 date for Marine Corps Marathon yet. The race is usually held in October, in Arlington / Washington D.C..
How many runners does the Marine Corps Marathon have?
That size is felt most in the opening kilometres, where the field is still bunched together.
Is the Marine Corps Marathon course difficult?
C. is broadly runnable. The main constraint is the density of runners through the early sections rather than anything in the terrain itself.
