Constantine is returning this spring, but she wants to bring others along with her in spirit.
Fundraising again for the Leukemia and Lymphoma Society, Constantine has issued what she's calling the "Boston Strong Virtual Fitness Challenge," a sort of "virtual Boston Marathon" that can be done from home or the gym or anywhere over the course of two months.
Constantine hopes the event can help her raise money for charity in the marathon, help local residents get in better shape.
"Over the years I've heard so many people say how they wish they were in better shape," she said.
It costs $26 to participate in the challenge, more information on it is available on its website.
