AS THE MARCHERS PASS THE 200-MILE MARK, TENSIONS REACH A BOILING POINT, AND A BIG SURPRISE AWAITS THEM IN NEW YORK CITY, ON ABC'S "FAT MARCH," AUGUST 20

"Episode 103" � The marchers rejoice as they exceed the 200-mile mark, but a huge blow up is in the offing among Matt, Will and Anthony, as tensions mount. Then, time stands still in Times Square when the walkers get a very big surprise in New York City, on "Fat March," MONDAY, AUGUST 20 (9:00-10:00 p.m., ET), on the ABC Television Network.

The marchers set out from New Haven, Connecticut with $80,000 prize money left for each contestant. Physical ailments are causing rapid deterioration: Matt's knees are in such pain that he feels they may be ruined beyond repair and worries that he may not be able to continue. Will struggles to get a grip on the physical and mental pressures that are impeding his ability to complete the journey; and Wendy is rushed to the hospital.

Anthony's dark side rears its ugly head and the others are beginning to suspect that he's a duplicitous and conniving instigator. The strain and stress pit Anthony against Will, and by the end of stage three, in Rye, New York, they take center stage for an even bigger brawl. A clam dig challenge splits the walkers into teams of two with the task of digging up as many clams as possible in a half-hour, and the psychological demands take a toll on another marcher who decides to leave.
