This enduring series, hosted by the Central Mass Striders, offers "cheap, no-frills racing for old pros and new runners" every Saturday, rain or shine, all year long. The 5K course starts and finishes right in front of Worcester State University, with registration conveniently located in Room 126 of the Sullivan Building. The route alternates directions weekly, running both clockwise and counter-clockwise, and was wheel-measured in 2019.

The CMS 52 Week 5K Series stands out for its unwavering commitment to providing a regular opportunity to run and connect with the local running community. While primarily a 5K event, participants can tackle a 10K option on the third Saturday of every month at no additional cost. Typical race day conditions in late October in Worcester see comfortable highs around 54°F and lows near 38°F, with only a 16% chance of precipitation, creating crisp autumn running weather. The focus here is squarely on the joy of running and consistent participation, making it a beloved fixture for many local runners.
