    Course

    The Boston Marathon course

    Point to point from Hopkinton to Boylston Street, run on Patriots' Day. Net downhill overall, which is exactly what makes it hard: the first miles drop fast enough to wreck your quads, and the Newton hills arrive at mile 16 when the damage is already done.

    Entry requires a qualifying time or a charity bib.

    Terrain
    Hilly
    Distances
    Marathon
    Weather on race day
    Notoriously variable. The same date has produced 40 degrees and driving rain, and 80 degrees and sun. A noon-ish start for many waves means you race in the warmest part of the day.

    What to train for

    Downhill running is the specific preparation this course demands, and it is the one most people skip.

    Build quads that hold up on long descents by practising sustained downhills in training, then treat the Newton hills as a pacing problem rather than a strength problem.

    Taper

    Tapering for the Boston Marathon

    Start the taper two to three weeks before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. The course is hilly, so keep one short hill session in the first taper week to keep the climbs familiar. With the race on April 19, 2027, your taper starts around April 1, 2027.

    Boston Marathon training questions

    How long should I train for the Boston Marathon?

    Most runners give a marathon sixteen to twenty weeks of focused training on top of an existing base. The plan above counts back from your actual race date, so if you have less time than that it builds the best plan the remaining weeks allow rather than pretending you have longer.

    Is the Boston Marathon course hilly?

    Hilly. Point to point from Hopkinton to Boylston Street, run on Patriots' Day.

    What is the weather usually like at the Boston Marathon?

    Notoriously variable. The same date has produced 40 degrees and driving rain, and 80 degrees and sun. A noon-ish start for many waves means you race in the warmest part of the day.

    When should I start tapering for the Boston Marathon?

    Start the taper two to three weeks before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. The course is hilly, so keep one short hill session in the first taper week to keep the climbs familiar. With the race on April 19, 2027, your taper starts around April 1, 2027.
