People survey the damage to barns at Churchill Downs after an apparent tornado struck the track in Louisville, Kentucky, June 23, 2011.
"Considering the damage, which is extensive, it is amazing -- borderline miraculous -- that there were no injuries to either humans or horses," said John Asher, Churchill Downs spokesman.
There was no damage to the grandstand or the track's iconic twin spires.
Churchill Downs is most famous for hosting the annual Kentucky Derby, the first leg in U.S. thoroughbred racing's Triple Crown of events, which also includes the Preakness and the Belmont Stakes.
Asher said crews on Thursday were inspecting the surface of the race track for storm debris, including nails, that might have been tossed onto the usually carefully manicured racing surface from the passing twister.
Six barns and a portion of a seventh were damaged severely enough they cannot be used, Asher said. Two others that had damage from the storm had been restored to service Thursday. As a result, 30 horses would be transported to Lexington where Keeneland raceway had offered temporary shelter.
