Description: ABC's weight loss reality competition pits twelve overweight contestants against each other for a cash prize of $1.2 million and an ultimate goal of better health. Beginning in Boston for the Boston Marathon, this series ends in Washington, DC as the contestants and two fitness trainers walk over 570 miles over nine states. The more people who cross the finish line, the more money each contestant walks away with. With a more healthy lifestyle as the end result, everyone wins. Based on Great Britain's Channel Four series, Too Big to Walk.
