DES MOINES, Iowa (AP) -- The Drake Relays says it is offering more than $500,000 in prize money in 2013 for a series of rematches from the London Olympics.

Meet organizers say they'll offer a $50,000 purse for invitational races and $25,000 for field events - the largest such purses in the U.S. Drake says it has lined up a rematch between the top three finishers of the men's 110 and the 400-meter hurdles.

Five gold medalists from London have agreed to compete next April at Drake, including U.S. pole vaulter Jenn Suhr and long jumper Brittney Reese.

South African double-amputee Oscar Pistorious is also slated to run in Iowa. U.S. hurdlers Dawn Wells and Kelly Wells are on board as well, though it's unclear if Des Moines native Lolo Jones will face her rivals.
