All Breeders' Cup Post-Race Samples Cleared by HIWU

All post-race test samples collected from contenders in the 2024 Breeders' Cup World Championships Nov. 1-2 at Del Mar have been cleared by the Horseracing Integrity and Welfare Unit, the enforcement arm of the Horseracing Integrity and Safety Authority. Purse distribution has begun accordingly. It was marked the second year the Breeders' Cup World Championships were run under the full jurisdiction of HISA, including the Anti-Doping and Medication Control Program, which took effect in May 2023. 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.
