Bill Rodgers Somerville Jingle Bell Run & Walk

Bill Rodgers Somerville Jingle Bell Run & Walk is held in Somerville, Massachusetts, on December 13, 2026. There is one distance on the program, a 5K, and it starts at 11:00 a.m. Runners and walkers share the same event, which makes it an easy December outing whether you are racing it or covering the distance at your own speed.

An 11 a.m. gun is a civilized way to race in December: no pre-dawn alarm, and enough time to eat, travel and warm up without rushing. For a 5K, warm up with ten to fifteen minutes of easy jogging and a handful of strides, then settle into an even pace from the first quarter mile. If you are building toward a spring goal, this fits neatly into a base phase as a hard effort that leaves your training week intact.
