A WEBSITE DEDICATED ONLY TO GRADE 1 HORSES
Why spend tens of thousands, hundreds of thousands, even millions of dollars to obtain what you hope will be top quality thoroughbred race horses without first examining the best information?
Why go down a breeding path well-trodden without giving yourself options for discovering other trails to future G-1 winners on dirt and turf, male and female, and over all distances, worldwide and specific to various geographic regions?
Even with the most popular and prolific sires, the chances of producing a G-1 winner or horse leading to same can be one in 50 or worse. However, the odds can be significantly improved by looking first at the actual winning sire-damsire combinations for G-1 races over the past four years and getting ahead of emerging trends.
G-1 Horse is now a subscription site in three parts:
- Part I–Five Generation Sire Circles of approximately 800 Group One/Grade One winning thoroughbred horses for the years 2021, 2022, 2023, and 2024.
- Part II, a Detailed Analysis of those Sire Circles presented in hundreds of easy-to-see and understand tables.
- Part III (available late 2025) with over 1,000 pages drawn from our Compendium of the detailed pedigrees of Group One/Grade One thoroughbred horses from the beginning of the G-1 era in 1971 to present time.
After several years of painstaking effort, we are offering these unique resources individually or together at affordable and flexible pricing. New and amended Sire Circles will be uploaded at regular intervals as 2025 G-1 racing results occur. Active subscribers may request additions to the site, in particular to pull out more pedigree secrets into the Detailed Analysis tables. We initiate Part II’s content with tables showing successful G-1 breeding sires, damsires, and sire-damsire combinations for all distances both by individual year and for the 2021 to 2024 period, worldwide and by geographic region.
WHO SHOULD BE INTERESTED IN G-1 THOROUGHBRED PEDIGREES, 2025 EDITION
We give present only facts, not opinions, with which you make decisions for breeding, purchasing, and racing thoroughbred horses. Serious-minded breeders, owners, and trainers determined to obtain a competitive advantage from pedigree information should consider making an investment in this product. All parts of our subscription web site come with hyperlinked indexes to find rapidly what you need. Five Generation Sire Circles can be located, for example, through a Master Index of G-1 winners and as well by race winner results for each of the 2021, 2022, 2023, and 2024 years.
HOW WE MADE OUR CONTENT
Horse by horse, race by race, we charted the actual pedigrees of Group One/Grade One winners from around the Northern Hemisphere (Europe, North America, the Near East, and Far East) for the entire Group One/Grade One period, beginning in 1971 in Europe, 1973 in the United States, and so forth. This methodology includes G-1 races that were later downgraded to lesser ranking or even discontinued. There are nearly 250 G-1 races that were run in the major thoroughbred racing nations of the Northern Hemisphere in 2023; over 100 have been downgraded or discontinued.
For the Southern Hemisphere, we concentrated on top thoroughbred winners of the 21st Century from Australia/New Zealand. To produce our Sire Circles and analysis, we covered all G-1 races in Australia since 2021. Any Southern Hemisphere thoroughbred that came out of South America and South Africa to win a Northern Hemisphere G-1 race in the last five decades is by virtue of that victory included. Total contests currently covered worldwide amount to about 330.
In our Compendium, we use a cross-referencing system based on sires so that the other half of a breeding pair that appears on a pedigree chart can be located through the Master Index. In this manner, the pedigree descent of a horse can be tracked back through multiple generations. Everyone knows the quality of major sires of recent and present time—the Curlins and Galileos, the Into Mischiefs and War Fronts. However, much like a newly discovered vein of gold in a hidden mine, other sire lines of lesser renown have yielded and are yielding high-quality thoroughbreds now achieving G-1 status.
This is why our Five Generation Sire Circles are so valuable. Although five generation pedigrees are not new, our method of presenting them is particularly useful at exposing superior breeding sires, damsires, etc. Results from Sire Circle collection are extracted, aggregated, and filtered to yield Detailed Analysis tables. The goal is to show at a glance where all the best pedigrees have come from around the world in the last four years.
Customized requests are possible, for example to focus on three year old fillies running the mile distance on grass in Europe, or a juvenile male dirt sprinter in the U.S., or a three and up thoroughbred of either gender winning multiple G-1s over longer distances in the Far East. In Part II, we provide a few specialty examples.
Centered on sires such as Northern Dancer and Raise a Native but also less prodigious but still important contributors such as Forli and Damascus, Boldnesian and Never Bend, Halo and Graustark, the Sire Groups in our Compendium have been responsible for producing the bulk of G-1 winners in the late 20th and early 21st Century.

ACCURACY OF INFORMATION
This project took years to accomplish and is ongoing for subsequent winner in G-1 races around the world. Although in assembling and organizing so much information human error is possible, our system of double-checking, triple-checking, and cross referencing with a “double entry” method of showing pedigrees from both sire and mare descents greatly reduces mistakes. We warrant that we have gone through all pedigree charts, Sire Circles, and Detailed Analysis tables page by page, often horse by horse to correct errors and ensure accuracy. Our goal is to provide customers with the best and most timely information possible.
