She tried her hand at the half marathon, resulting in a win at the City-Pier-City Loop in 1993 and a fourth-place finish at the 1995 IAAF World Half Marathon Championships. She also won the Honolulu Marathon that year with a time of 2:37:29. In 1996 she won the Lilac Bloomsday Run, the Berlin Marathon, and the Eurocross cross country meeting in Luxembourg. She made her second Olympic appearance in the 10,000 m, taking 13th place at the 1996 Atlanta Olympics.
Her first appearance on the world championships stage came at the 1997 World Championships in Athletics and she finished in eighth in the final of the 10,000 meters. At the 1998 IAAF World Cross Country Championships she finished in 15th overall in the women's long race. Following a missed opportunity at the 1999 World Championships in Athletics, she represented South Africa at the Olympics for the third and final time, but managed on 31st place in the women's marathon with a time of 2:36:58.
After making a nationality transfer, De Reuck made her first appearance for "Team USA" at the 2002 World Cross Country Championships in Dublin, Ireland, where she finished third overall (27:17) and helped the United States team to a silver medal. The following year she finished in seventh place at the 2003 World Cross Country Championships, helping the U.S. team to the bronze medal. She made her fourth and final Olympics the 2004 Athens Olympics. She finished in 39th place in the marathon, while U.S. teammate Deena Kastor won the bronze medal.
She won the USA Cross Country Championships twice consecutively in 2004 and 2005. De Reuck represented the United States twice more at the World Cross Country Championships, finishing in 13th place in 2005, and 33rd place at her final competition in 2006 at age 41.

Just nine days earlier she had run 2:32:37 at the Twin Cities Marathon in St. Paul, Minnesota beating the listed American W45 record by over 6 minutes.
She ran at the Falmouth Road Race in Massachusetts in August 2010 and took fifth place as the first American past the line. Shortly after she ran in the Copenhagen Marathon in Denmark and placed 1st in 2:30:51, 8 minutes ahead of her nearest opponent.
