Fastest horses: These are Sunday's top HRN speed figures
Snowyte led all performers Sunday with a 127 Horse Racing Nation speed figure in a 1 1/16-mile allowance-optional claiming race on the Gulfstream dirt. The daughter of Good Magic, trained by Danny Gargan, was making her 4-year-old debut. She shot to the early lead and never let anyone challenge her, drawing off to win by 11 1/4 lengths at 3-2 odds. It was her second win in eight career starts, and she also was second in the 2024 Frizette (G1) while still a maiden.
Fran's Star earned a 123 HRN speed figure at Fair Grounds in a second-level Louisiana-bred optional-claiming allowance turf mile. A 5-year-old Star Guitar gelding trained by Shane Wilson, he chased the pace before rallying in the lane to finish 1 3/4 lengths clear of the pack. It was his third win from 19 starts and his first victory since December of 2024.
Forced Entry had the joint third-best HRN speed figure of Sunday, earning a 120 in a maiden special weight dirt mile at Santa Anita. The 3-year-old Charlatan filly, trained by Bob Baffert, led at every call and cruised clear to win by 7 1/4 lengths at 7-2 odds. This second career start was a sharp improvement over her debut Jan. 11, when she weakened to last of 10 after getting bumped in upper stretch.
City Exile also earned a 120 HRN speed figure Sunday in a starter allowance at 1 1/8 miles on the Santa Anita turf. Sent off the 4-5 favorite in a field of six, he settled toward the rear of the field early but rallied strongly into the lane and cleared off to win by 3 1/2 lengths. The 6-year-old Cityscape gelding, trained by George Papaprodromou, earned the third win of his 19-race career. This was his first victory since an allowance-optional claiming race in July of 2024 at Del Mar.

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.
