Speed figures: See Thursday's fastest from coast to coast
Who's the King led all performers on Thursday with a 135 Horse Racing Nation speed figure in a starter-optional claiming dirt mile at Laurel Park. The 5-year-old Not This Time gelding, trained by Jamie Ness, led at every call and drew off to win by seven lengths as the 3-2 favorite. It was his third career win in 22 starts and his first victory since a claiming-level score last July at Saratoga.
Chaos Agent earned a 133 HRN speed figure in his debut Thursday at Gulfstream in a 1 1/16-mile route over the Tapeta. The 3-year-old Independence Hall colt was dismissed at 11-1 in a field of seven, but came ready to run for trainer Josie Carroll. He tracked the pace before rallying in the lane to win by 1 1/2 lengths.
Twelve Treasures completed the top three, also earning a 133 HRN speed figure Thursday. His win came in a seven-furlong claiming sprint over the dirt at Tampa Bay Downs. The 4-year-old son of Candy Ride, trained by Renaldo Richards, attended the pace before rolling clear in the lane to win by 6 1/2 lengths at a 5-1 price. He won for the third time in his 11-race career and the second time this year.

About HRN speed figures
HRN speed figures are AI-generated using HRN's proprietary machine-learning algorithms. Although they involve less human input than other speed figures, we see that as a plus as human adjustments often knock down surprisingly good performances to match expectations. HRN speed figures were launched in December 2024, and our expectation is also that the AI-generated speed figures will continuously get better over time.
The HRN speed figure scale goes from 1 to 160. Part of the reason for this higher scale is this helps us avoid assigning a speed figure of zero. For some products, in weaker races, half the field or more may get a speed figure of zero, which leads to inaccuracy and defeats the purpose of speed figures.
Because the HRN speed figures are based on machine learning, as we improve our models we can compute the numbers historically.
Using the top last-race speed figure as a benchmark, here are stats from 2021 to 2024 for HRN and other speed-figure providers:
Top HRN figure 26.2% winners
Top Beyer figure 28.1% winners
Top TimeformUS figure 28.4% winners
Although all HRN speed figures are published on individual horse profile pages on a weekly basis, the daily reports are focused on the top and medium-tier tracks, which represent the majority of top speed figures.
Note: For the fastest maiden winners mentioned, all dam and sibling earnings are based on North American starts only.
