Cambridge Half Marathon Spectator Guide

October 9, 2026 · 5 min read

Where to watch the Cambridge Half: CambridgeSide start and finish, one walk on the Charles, no drive on Memorial Drive.

The Cambridge Half starts and finishes at CambridgeSide. The course is a flat loop on the Charles. You can see a runner twice without a car.

CambridgeSide

The mall side of the finish is the base. A walk across the river and back is the second look. Memorial Drive is closed. Do not try to drive it.

  • Base: CambridgeSide, off the course.
  • Second look: the bridge loop, on foot.
  • Halloween weekend. Costumes are common. Leave a gap for runners.

Getting there

Red Line to Kendall or Charles, then a walk. Other Massachusetts half marathons are not this tight to the river.
