In a tumultuous year for Thoroughbred racing, synthetic surfaces again became a major point of discussion. A number of major racetracks switched to synthetic surfaces in the 2000s, including the Southern California circuit – which found itself in the center of the storm regarding equine welfare in 2019 – and Keeneland. However, most tracks eventually reverted back to traditional dirt surfaces, as they struggled with maintenance or faced complaints from a variety of racing groups, including breeders, handicappers, and trainers.
