In recent years, Kastor has shifted her focus toward the marathon distance. After winning the bronze medal at the 2004 Olympic Marathon, she won the 2005 Chicago Marathon.

She placed sixth at the 2006 New York City Marathon and fifth at the 2007 Boston Marathon. Kastor is a featured subject in the 2007 marathon documentary Spirit of the Marathon, which follows her victory at the 2005 Chicago Marathon.
In April 2008, Kastor won the U.S. women's Olympic marathon trials in Boston, Massachusetts. She finished with an unofficial time of 2:29:35, after overtaking competitor Magdalena Lewy Boulet in mile 23. Kastor ran most of the race from behind, while Lewy Boulet built a commanding lead very early on, running alone for most of the marathon. With some 10 miles (16 km) to go, Kastor made a move to catch up to Lewy Boulet, stringing out the field. Lewy Boulet took second place in 2:30:19.
In August 2008, Kastor pulled out of the women's marathon at the Beijing Olympics with a foot injury. At about the 5-kilometer (3.1 mi) mark, she dropped to one knee, holding her right foot. She attempted to rise, but dropped back down again and was forced to withdraw from the race.
On March 21, 2010, Kastor competed in the first spring running of the New York City Half Marathon. After running the majority of the race in first, on her way to breaking the course record, she dropped to second place to finish behind Great Britain's Mara Yamauchi.
