Speed figs: See the day's fastest horses and maiden winners
We the Hobby posted the day's highest Horse Racing Nation speed figure with a 124 performance at Del Mar in the eighth race. The 3-year-old filly by Om, trained by Peter Miller, captured a one-mile turf maiden special weight. She stalked the pace and wore down pacesetter Ridegold to win by a half length as the narrow 3-1 favorite. This marked her first career victory in her 10th career start, after hitting the board seven times before Friday.
Grand Opening earned a 121 HRN speed figure at Colonial Downs in a 6 1/2-furlong allowance optional claimer on Friday. The 4-year-old gelding by Union Jackson won at 4-5 odds, rallying from last in a tightly bunched field of six and getting up by a neck. The W. Robert Bailes trainee won for the fourth time in nine starts.
Usha completed the top three with a 119 HRN speed figure at Del Mar in a 6 1/2-furlong dirt allowance optional claimer. The 3-year-old filly by Tiz the Law, trained by Bob Baffert, was bet down to 2-5 in the eight-horse field. She let at every call, clearing off on the turn and winning by 5 1/4 lengths. Though she was winless in four starts as a juvenile, she has come back strong as a sophomore, winning both starts of the year so far.

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.
