Speed figures: Daily top 10 and the fastest maiden winners
A deep-closing, worst-to-first victory in the Grade 2, $400,000 Phoenix Stakes earned veteran Nakatomi a berth in the Breeders’ Cup Sprint. It also was worthy of Friday’s top Horse Racing Nation speed figure.
The 6-year-old gelding with more than $1.7 million in earnings led all performers with a 134 HRN figure at Keeneland. Coming through at odds of 8-5, Nakatomi is a seven-time winner in 24 starts.
Sweetest Princess earned a 127 Hat Belmont at Aqueduct in a one-mile dirt claiming race. The 5-year-old mare by Cairo Prince won at 3-1 odds in a dominant fashion by 3 1/2 lengths in her 32nd career start. This marked her fifth career victory.
Dettori completed the top three with a 125 at Belmont at Aqueduct in a one-mile dirt race for maidens. The 3-year-old colt by Munnings scored at 16-1, recording his first career win from five starts. He is out of Grade 3 winner Hit It Rich, who earned $522,000.

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.
