Tuesday 20 October 2026 racing: the card at Yarmouth, Curragh and two more

← Every day·Today's market·Today so far·Results for Wednesday, 4 November 2026

This is the card for Tuesday, 20 October 2026, kept as an archive. The latest cards are here.

The card for Tuesday 20 October 2026 runs to four meetings and 30 races: Curragh in Ireland, and Yarmouth, Hexham and Newcastle in Britain. The first race is at Yarmouth at 13:20 and the last is at Newcastle at 20:30. The longest card of the day is at Newcastle, which offers a full programme of Flat racing, while the Curragh provides the Irish interest. The feature is the Graham & Alison's 15th Wedding Aniversary Novice Stakes at Yarmouth, due off at 14:20, and it has the next section to itself. Every runner, with the model's estimated chance beside the market's price, is on the racecards page, and the model's view of the whole day is on the day's predictions; the card was written before the first race, so nothing on it is a result.

The model rated March Of Time its most likely winner at 37%, ahead of Starship Lily (26%) and Kohana Girl (17%). It read as a clear first choice, but beatable.

These were the model's estimated win chances going into the race, not tips. The model is calibrated to real results (when it says 25%, about 25% win) but it does not beat the market, so read it as an independent second opinion on the race. See how accurate it is →

Model: ensemble-v1.1 · Generated Tue, 20 Oct 2026The LabMethodology

The model and the market prefer different horses in the feature, with March Of Time rated highest by the model and Starship Lily by the market. The card above sets the model's estimated chance for each runner beside the chance implied by the market, and the gap between the two columns is the only thing the Lab claims to measure; it says which horse the model rates highest and nothing about what to do with that. The race is run over 5f42y, on ground declared as Soft, with six priced runners. The course itself is covered in the Yarmouth guide.

Where the model disagrees with the market

The widest gap between the model's estimate and the market's price on this card is in the Every Race, Every Moment 1xBet.ie Amateur Riders Derby (Q.R.) Race at Curragh (15:35), where the model gives Absurde a smaller chance than the price implies. The race was chosen by the size of that gap and by nothing else.

Model: ensemble-v1.1 · Generated Tue, 20 Oct 2026The LabMethodology

A gap is a difference of opinion, and a difference of opinion is all it is: the wide ones tend to fall on runners the model has the least evidence about, as often as on a horse the market has overlooked. The left column is the model's estimated chance, the right is the chance the price implies, and the track record shows how often the model's side of the argument has been right once every pick is settled at starting price.

What the card costs

Every price on the card carries the bookmaker's margin: add up the chances the prices imply and the total comes to more than a whole field, and the excess is what the book keeps whichever horse wins. The table below is the latest published margin for each book the Lab tracks. It is compiled from the previous evening's prices, so it describes the card as it was sold then rather than the morning's board, and the order of the table is a measurement, never a recommendation.

First pre-race book of each day, 2026-08-27 to 2026-11-03, across 2483 races every listed book priced in full. Exchanges and spread firms are excluded: they do not quote comparable win odds. Overround is how far past a fair book the prices sit; takeout is the share of stakes the book keeps. On 67 days of data, books marked = are level with the one above rather than behind it. Books marked "shared feed" are one half of a pair that does not price independently, so there are fewer independent books here than rows.

The margin is the reason the Lab's tested strategies lose over time even when a pick is sound; what betting costs has the working, and the Tipster League shows what it does to the AI tipsters over a season.

Common questions

Which meetings race on Tuesday 20 October 2026?

Curragh in Ireland, and Yarmouth, Hexham and Newcastle in Britain. Every card is on the racecards page with the model's estimated chance beside each runner, and the first race is at Yarmouth at 13:20.

When are the model's estimates published?

Each morning before the first race, from the declared runners, and they are not changed after the off. A card labels itself a pre-race estimate once its race has run.

What does the model's chance mean?

The model's own estimate of how likely each runner is to win, set beside the chance the market price implies. It is an opinion with a published record, not a tip, and the track record is where that record lives.

Why is a horse missing from a card?

Either it was withdrawn after the estimates were made, or the race was one the model did not price. The horse tracker follows any runner on the card to its next entry.

How are the AI tipsters doing?

The Tipster League settles every AI pick at starting price and publishes the running total, losses included.

A word on all of this

None of the above is a tip, and no system the Lab has tested has made money over the whole record. Bet only what you can afford to lose. If gambling has stopped being fun, BeGambleAware has free, confidential help.

Every figure on this page renders live from our published feeds and nothing here is a tip. For whether the model holds any edge, see our track record. 18+, please bet responsibly.
