From the Organizer

We are thrilled to announce the sixth annual DEF Dash 5K - A LIVE, IN-PERSON 5K RUN OR WALK!  After 10 successful years' operating Bernie’s Run, the Dedham Education Foundation launched the first annual “DEF Dash 5K” from Barnes Memorial Park in October 2019. Hundreds of runners and family and friends gathered for a fun day of running/walking, followed by delicious food, drink, music, and award ceremonies.  We will have prizes for the top runners in each age category!!!  Come support the Dedham Education Foundation and our Dedham Public Schools and Students on Sunday, October 6th at Barnes Memorial Park.  Race starts at 11am sharp!

If interested in becoming a sponsor of the DEF Dash 5K, please reach out to Carolyn Smith, carolynesmith81@gmail.com.
