In colorful yet tasteful burger suits, the Burger Brigade redefines fast food. Tomorrow, from 4 to 6 p.m., the group will be serving free b. good shakes and Ben & Jerry’s ice cream in front of b. good on Dunster Street.

The brigade is sponsored by b. good, and has a simple concept: "a bunch of Harvard students dress up as burgers while running the Boston Marathon to raise money for charity," said team member Amy Guan '12.

The team hopes to raise funds and awareness for Back on My Feet, a charity that works with the homeless to promote independence and self-sufficiency. Last year's Burger Brigade raised $17,000 for the charity, and this year's team hopes to top that sum by $2,000.

Need a greater incentive to stop by the event? A couple of runners will also be present in full burger costumes. While they are inspired by taste, running 26.2 miles in a burger outfit might be tricky.

"They say they're aerodynamic, but it is essentially a tire with cloth around it," Guan said with trepidation.

The event's Facebook page can be found here.
