Welcome to Sprint Paddock!

Sprint Paddock is a platform that lets you move seamlessly from race predictions powered by our proprietary AI index, the “SI Index,” to detailed analysis of historical data and management of your own betting profit/loss. We cover not only JRA (central) racing but also NAR (regional) racing.

For first-time users, here is how to use the three main features, step by step.

Make the most of AI predictions (SI Index)

Check each runner’s objective ability rating and win-probability forecast to help you study a race.

• Check the entry table & index list: Select a race to see each horse’s basic information along with its “SI Index” (our proprietary ability index) and the win-probability ranking.
• Check recommended races & tickets: Based on the SI Index and expected value calculated by Sprint AI, you can see marks such as the top pick and second pick, the races recommended for betting, and the recommended tickets.
• Past hit rate & recovery rate: We publish the AI model’s past track record and weekly hit/recovery rates, so you can check its accuracy with a high level of transparency.

Dig deeper with the racing database

Quickly research the horses, jockeys, and race trends that interest you.

• Horse & jockey search: Enter a horse or jockey name in the search bar to instantly see past records, course-by-course win rates, favoured conditions, and more.
• Race / condition trend analysis: Refer to historical data by racecourse, distance, and going, and use it to test your own handicapping logic.

Look back with Umakeibo (P/L management)

Umakeibo is Sprint Paddock’s original profit/loss system that records and analyzes the tickets you buy to help improve your recovery rate. Give it a try!

You can easily enter, for each race, the ticket type, selections, and stake — either from each race’s AI prediction page or from the Umakeibo page.

• Automatic tallying & recovery-rate visualization: Hits and payouts are calculated automatically, so your monthly, yearly, and ticket-type P/L graphs and recovery rates are visible at a glance.
• Data-driven review: Analyze your own buying tendencies — which ticket types you are good at, which racecourses you are in the black at, and so on.

Creating a (free) account & linking accounts

You can use some basic features of Sprint Paddock without registering, but creating a free account unlocks all of the convenient features.

• Easy social login: In addition to email, you can register and log in with one click using your Google, LINE, or X (formerly Twitter) account.
• Automatic data sync: Once registered, your Umakeibo P/L data and favourite settings sync automatically across your smartphone and PC.
