"The new 'Subway' will enjoy free sandwiches for life from Subway's biggest refresh yet, following the debut of freshly sliced meats in U.S. restaurants and elevating its entire menu earlier this summer with a new line up of Deli Hero subs to its Subway Series menu," the release read.

"In addition, the winner will receive money to reimburse legal and processing costs to complete the name change process."

Announced on July 26, the "Name Change Challenge" strives to represent the brand's love and dedication to its fans.
