All post-race test samples taken from contenders in the 2024 Breeders' Cup World Championships Nov. 1-2 at Del Mar Thoroughbred Club have been cleared by the Horseracing Integrity & Welfare Unit (HIWU), the Breeders' Cup announced Monday and purse distribution has begun accordingly.
2024 marked the second year the Breeders' Cup World Championships were run under the full jurisdiction of the Horseracing Integrity & Safety Authority (HISA), including the Anti-Doping and Medication Control (ADMC) Program, which took effect in May of 2023 and is implemented and enforced by HIWU.
As was the case under Breeders' Cup's anti-doping and medication control rules that were in place before HISA's ADMC Program was implemented, medication is prohibited within 48 hours of the 14 Championship races and the undercard. All potential Breeders' Cup competitors were also subject to out-of-competition testing for banned substances leading up to the event.
