Some of the most famous racers are Irineo Leguisamo, Vilmar Sanguinetti, Marina Lezcano, Jorge Valdivieso, Pablo Falero and Jorge Ricardo. Carlos Gardel's tango Por una cabeza is about horse racing, a sport of which he was a known fan. Gardel was a good friend of Irineo Leguisamo, who is the most recognized Uruguayan jockey, who raced numerous years in Argentine. Betting At many horse races, there is a gambling station, where gamblers can stake money on a horse. Gambling on horses is prohibited at some tracks; Springdale Race Course, home of the nationally renowned TD Bank Carolina Cup and Colonial Cup Steeplechase in Camden, South Carolina, is known as one of the tracks where betting is illegal, due to a 1951 law.

She added that almost 20% of these were serious head or neck injuries. The study reported 6,545 injuries during the years 1993–1996. More than 100 jockeys were killed in the United States between 1950 and 1987. Horses also face dangers in racing. 1.5 horses die out of every 1,000 starts in the United States. The U.S. Jockey Club in New York estimates that about 600 horses died at racetracks in 2006. Another estimates there are 1,000 deaths annual in the US. The Jockey Club in Hong Kong reported a far lower figure of 0.58 horses per 1,000 starts. There is speculation that drugs used in horse racing in
