About

mazetick is a data site for UK and Irish horse racing. The product is not a prediction and not a selection. It is our own count over published race results, with the date it was true on every figure.

Why that, and not a card

Racing Post, Sporting Life and At The Races already publish the racecard, the form and the prices, free, and better than we would. Reproducing them would add nothing.

What we add is the whole record rather than a rolling fortnight: each horse’s runs split by going, by course and by distance, its jockey and trainer figures, and its sire’s progeny under the same conditions — each rate with its sample beside it, and each page with the date the archive runs to.

What we will not do

We do not sell selections and we do not promise a return. That is not modesty. It is the result of two years of trying to beat these markets with machine learning and with classic handicapping rules, and measuring honestly enough to find that neither worked. The market price already contains what we knew, and more.

We published those measurements here for a time. They were built on bookmaker and exchange prices that we are not licensed to publish, so on 8 November 2026 we withdrew them, together with the pages that showed each-way terms and exchange order books.

How the numbers are made

• Every figure carries its timestamp. A table without an "as of" is somebody else's product, not ours.
• No look-ahead. A statistic about a race uses only information that existed before it was run. This sounds obvious and is the single most common way racing statistics are overstated — including, at times, our own.
• Sample and window on the page. If a rate is computed from twelve runs, it says twelve.
• Negative results get published. They are the most defensible thing we own.

Where the data comes from

Race records and results come from a licensed racing data feed and from an archive of published race results. Derived statistics — strike rates by going, by course, by distance — are our own calculations over those records, and are described where they appear. No bookmaker or exchange price is shown on this site.

Who runs this

mazetick is run by one person, Bruno Masello, an individual based in Brazil. There is no company behind it and no staff. The “we” on these pages is editorial: the collection, the calculations, the writing and the mistakes are his.

mazetick is not a bookmaker. It takes no bets, holds no customer money and holds no gambling licence; it publishes measurements. As the terms say, at the time of writing it carries no paid links of any kind. If that changes, this page will say who pays, and since when.

The code that builds the site is public at github.com/bumasello/mazetick, and so are the data files it publishes, at github.com/bumasello/mazetick-data.
