Eight Belles will be interred at the Kentucky Derby Museum, near the grave sites of four Kentucky Derby winners.
The 3-year-old filly broke two ankles after finishing second to Big Brown in the Kentucky Derby on May 3. She was euthanized on the track.
The track said Tuesday it will plant a tree in honor of Eight Belles and her remains will be buried at its base. The memorial is planned for the museum's courtyard, with the date still to be set.
Churchill Downs will rename the $150,000-added La Troienne in honor of Eight Belles. The Grade III stakes race for 3-year-old fillies will continue to be run on the Kentucky Derby day undercard. The track also plans a ceremony on Derby day in 2009 in the filly's memory.
Steve Sexton, executive vice president of Churchill Downs Inc., said the track's foundation will contribute $25,000 to the Eight Belles Memorial Fund. The fund, established by Thoroughbred Charities of America, is aimed at researching racehorse injuries and retraining retired thoroughbreds. The contribution will be matched by Eight Belles owner Rick Porter.
