Lace up your running shoes for the CMS 52 Week 5K Series, an enduring staple in the Worcester, MA running community. Taking place on January 31, 2026, this consistent 5K offers a fantastic opportunity to stay active through the winter months. The race, hosted by the Central Mass Striders, has a rich history as a year-round, "rain or shine" event, known for its no-frills approach that welcomes both seasoned runners and those new to the sport.

The course is set at Worcester State University, with the start and finish lines positioned directly in front of the campus. Runners can expect a wheel-measured 5K route, which uniquely alternates between clockwise and counter-clockwise directions, adding a fresh challenge each week. Typical race day conditions in late January can be brisk, with historical highs around 33°F and lows near 17°F, and about a 15% chance of precipitation, so prepare for a chilly, invigorating run.

The CMS 52 Week 5K Series stands out for its accessibility and dedication to fostering a consistent running environment. Registration is conveniently held in-person starting at 8:15 AM in Room 126 of the Sullivan Building at Worcester State University. This event focuses on the joy of running and community, making it an excellent choice for anyone looking for a regular, low-key race experience.
