Green also included a special message to Celtics assistant coach Jamie Young, who is running the marathon for the first time. Young, a holdover from former coach Doc Rivers’ staff, is from Indiana but considers himself a New Englander after 13 years with the Celtics.

Young is running on behalf of the Shamrock Foundation.
