The 11th Annual BFit Challenge powered by National Grid returns on Sunday, January 31, 2027, bringing together supporters, first responders, military personnel, and community members for one unforgettable day at TD Garden. Whether you walk, run, or simply rally behind the cause, you'll be helping raise critical funds for First Responder and Military charities that make a difference every day. Since its inception, the BFit Challenge has generated more than $6.4 million in support of these deserving organizations. This event isn't a race against others. It's a challenge to give back. Participants aged 16 and up and all fitness levels are welcome, and 100% of the funds you raise go directly to the First Responder or Military BFit host charity of your choice at registration. Each participant commits to raising a minimum of $300, turning every step around TD Garden into meaningful support for those who serve our New England communities. Don't forget to join us for after parties at Banners Kitchen & Tap and Big Night Live! Register today, fundraise with purpose, and be part of something bigger than yourself.
