ABC's new show Fat March debuts Monday night. On Fat March, 12 overweight people are challenged to walk from the starting line for the Boston Marathon to Washington DC. According to ABC, their journey will be more than 570 miles. The goal will be to drop unwanted pounds, get fit, and win some cash and prizes along the way. Team work will be rewarded on Fat March -- The more people who reach the finish line, the more money all participants win from a prize pool of $1.2 million. Adding to the drama, marchers who are holding back the rest of the team may be chosen for elimination.

The show's time slot is Monday nights at 9:00-10:00 p.m. ET/PT.
