The endurance competition at the Alltech FEI World Equestrian Games has been marred by the death of a horse on the first loop, as 19 other horses failed to get through the first vet check.
Costa Rican rider Claudia Romero Chacon and Dorado fell 13.6kms into the first loop and just 400 metres short of the first check point on the course, at about 8.30am local time.
Dorado (Siroko x Catrina / Rey Mago), a 12-year-old gelding, was fatally injured in the fall, and Chacon, who remained conscious, was taken to hospital by ambulance, organisers say. No other details about the accident were available.
Dorado (Siroko x Catrina / Rey Mago) was a 12-year-old gelding, owned by Jorge Eduardo Vargas Jenkins. According to FEI records it was his third 160km ride, and Chacon had been riding the horse since last December.
Update: An investigation by the FEI shows that Dorado struck a tree at the side of the track in a forested area. He sustained a head injury and died instantly. There were no signs that Dorado slipped before the impact. More
