About the Cambridge Half Marathon
Boston-area runners treat this as the closing time trial of the road season, and the field has grown into the thousands since the first edition. A large charity partner program runs alongside standard entry, and the weekend pairs the Sunday half with a Saturday 5K and a combined challenge.
Course
Start and finish sit at CambridgeSide, and the certified route runs out along Memorial Drive on the Charles River. Runners pass MIT, the Weeks Footbridge, and Harvard Stadium with almost no elevation change, which makes this a genuine PR setup rather than a scenic tour.
Race-day weather
Early November in Cambridge lands close to ideal for a half, often in the forties at the seven o'clock start. The exposed river sections are where wind shows up, and a headwind along Memorial Drive can take back more than the flat profile gives.
