Can you guess the fastest horse of 2025? Answer: Sovereignty, who earned a 115 Beyer Speed Figure in this year's GI Travers Stakes. That number was also the fastest Beyer of the last seven years by any horse other than Flightline. The Fastest Horse of the Year is brought to you by WinStar Farm, who welcomes three new stallions to their roster for 2026 in Straight No Chaser, Mullikin and Patch Adams.
