11th Annual JB Blastoff 5K Walk/Run
Sunday, October 4, 2020

Postponed until 2021.  We will keep you updated with a date once it is set.  Thank you for understanding.


This years mission will benefit a Waltham family that recently lost a loved one.  In 2005 my dad, Joseph Basile passed away from a Glioblastoma brain tumor.  This race has raised thousands of dollars for cancer research over the past 10 years in his name.  This years proceeds will go to Officer Charles (Charlie) Gryska's family. Charlie passed away from brain cancer on December 6, 2019.  Officer Gryska cherished spending time with family, especially his wife and three children. He loved “date nights” with his wife, Jackie, and he found great pride in watching his son, Jack, play soccer, his son, Bryce attend his first day of pre-school and his daughter, Abby, take her first steps. He also loved spending time with his family during the summer on Cape Cod and in Maine. I’m asking you to support the Gryska family by registering for the JB Blastoff 5K.  #teamgryska
