The "Run/Walk BOOM!!!" races are June 29. Last year's inaugural Huntington Woods event attracted hundreds of participants, raising thousands of dollars.
Entry forms and fliers are already on display, and T-shirts have been ordered.
Alex Cooper, a member of the committee organizing the event, said there are strong opinions on both sides, including some who say renaming it would be "giving in to terrorism."
To help settle the issue, organizers posted a survey on the event's website. Regardless of a decision, a moment of silence is planned at the start of the races to honor Boston victims.
