The 40-year-old mom will run the marathon.
Deena Kastor, who holds U.S. records for the half-marathon and marathon distances, was added to the U.S. marathon team that will compete at the world championships this summer in Moscow.
Her agent Ray Flynn broke the news on Twitter Friday morning.
“Deena selected to US World Championships Marathon Team 2013! and will compete in Moscow,” he Tweeted.
The 40-year-old Kastor’s most recent 26.2-mile jaunt was the Los Angeles Marathon in March, in which she placed third in 2:32:39. She set American records in the marathon (2:19:36) and half-marathon (1:07.34) in 2006. Both of those marks still stand.
Also this season, Kastor finished third at the U.S. Cross Country Championships, and then placed 34th at the World Cross Country Championships in Poland, held one week after the L.A. Marathon.
Last month, Kastor won the More/Fitness Half Marathon in New York City, stopping the clock in 1:13:25.
Kastor won the bronze medal in the marathon at the 2004 Athens Olympics. Four years later in Beijing, she pulled out of the race because of a foot injury. She placed sixth at the 2012 Olympic Marathon Trials in Houston.
The World Championships take place Aug. 10-18 in Moscow. The women’s marathon is scheduled for the first day of competition, while the men’s race is on Day 8.
