Boston Marathon 2027 race week
Boston, USA · Apr 19, 2027
Race week has four jobs: get your bib, keep your legs fresh, run one short shakeout, and start rested. Below is the day-by-day plan for the Boston Marathon, plus the heart-shaped 3-5K to run through Boston the morning before the start.
Your race-week plan
- Friday Apr 16 — Travel & expo. Land, collect your bib, and stay off your feet once the expo is done. Walking Boston for six hours is the classic race-week mistake.
- Saturday Apr 17 — Easy legs. A short 20-30 minute jog or nothing at all. Eat normally, hydrate, and get your kit laid out early.
- Sunday Apr 18 — Shakeout heart. The one run that matters this week: 3-5K easy through Boston, shaped like a heart. Loose legs, calm head, and something to post the night before.
- Monday Apr 19 — Race day. Everything is already done. Run the race you trained for.
Shakeout runs in Boston
Brands, stores, and run clubs announce free race-week shakeouts a few weeks out, and verified meeting points appear on this page when they do. You can also build your own heart-shaped route through Boston, export the GPX for Garmin, Coros, or Apple Watch, and invite whoever else is racing.
Race-week questions
When should I do my shakeout run before the Boston Marathon?
The day before the race, Sunday Apr 18, morning if you can. Keep it to 3-5K at conversational pace, then stay off your feet.
What should I run the day before the Boston Marathon?
A short easy loop through Boston. CityHeart builds a heart-shaped 3-5K on real streets, exports it as GPX for Garmin, Coros, or Apple Watch, and it shows up as GPS art on Strava after your run.
