Officials at Keeneland are confirming that this will be the last meet to feature polytrack.
The synthetic surface is a blend of rubber, sand, fiber, and wax piled on top of a hard, porous, asphalt base.
The Louisville Courier Journal reports that track officials have made the decision to return to a mixture of clay, sand, and silt this fall.
Keeneland President and CEO Bill Thomason tells the paper while injuries have decreased since the installation of polytrack, in 2006, not enough other horse tracks followed suit, and they feared not being able to attract the top thoroughbreds to Lexington.
Keeneland joins the Del Mar Thoroughbred Club near San Diego as the latest facilities to dump polytrack, which at one time was considered the wave of the future.
The switch to dirt coincides with an effort by Keeneland to host the 2015 Breeders’ Cup.
