Calling all runners, walkers, and joggers: The seventh annual BFit Challenge, powered by National Grid, is happening on Sunday, Feb. 5 from 9 a.m.-1 p.m. This one-of-a-kind event invites first responders, military members, and anyone in the community to exercise around TD Garden, home of the Boston Bruins. The challenge is hosted by the Boston Bruins Foundation, which collaborates with charitable organizations that demonstrate a commitment to health and wellness, education, and athletics.

Registration is $25, and each participant has to fundraise $300 as individuals or as part of a team (max. 10 people). 100% of the money raised goes to first responder and military charities. Last year, the event raised $425,000. This year, organizers hope to raise $600,000 to benefit local first responder and military charities. Bonus: If you meet specific fundraising goals, you'll win prizes like autographed hockey pucks and jerseys signed by Bruins players. 🏒

Here's how the challenge works:
This fitness fundraiser has various levels throughout TD Garden, which are accessible for first-time exercisers but also levels to challenge the most elite athletes. Each different level consists of stairs and laps around TD Garden. This year, an exciting new level brings the most elite participants into the Verizon Tower for a more traditional stair climb — all the way from Level 8 of TD Garden to the new Bruins offices on Level 14 and then back down.

Can't make it to the in-person event? Anyone can participate in a virtual step challenge happening from Friday, Jan. 27-Friday, Feb. 3.
