Prepare for Boston Marathon

A plan built from your answers and your race date.

The Boston Marathon runs point to point on pavement from the western Massachusetts suburbs into downtown Boston. The route passes through a string of small towns before entering the city, with dense crowds along nearly the entire course. It falls on Patriots' Day, the third Monday in April, which makes race day a civic event as much as a sporting one.

The race is part of the Abbott World Marathon Majors and is known above all for how hard it is to get into. A. announcements closely before building a season around this race.

When to start

A build for this distance usually runs 12 to 20 weeks. Counted back from race day, that puts the start somewhere between November 30, 2026 and January 25, 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.

195 km point-to-point with a deceptive profile: a pronounced early descent that loads the quadriceps, then a series of climbs in the second half that punishes anyone who started too fast.
