Horse racing betting: each-way, best odds guaranteed, Rule 4 and the exchange

The oldest betting market and the one with the most rules of its own. What each-way really pays, why best odds guaranteed matters, how a non-runner changes your price, and where the exchange beats every bookmaker.

Key points

  • Each-way terms and best odds guaranteed are worth more than the headline price; compare them before the odds.
  • A non-runner triggers a Rule 4 deduction from your winnings; the size depends on the withdrawn horse’s price.
  • On the exchange, horses trade at prices the bookmakers cannot match, and winning is not punished.

The bets

Win. The horse must win. Each-way. Two bets: win and place, the place part paid at a fraction of the win odds for a set number of places, usually a quarter for three places in fields of eight or more, a fifth for four places in big handicaps. Place only and forecast bets exist but are priced expensively. Ante-post. Bets placed days or weeks before a big race at bigger prices, with the stake lost if the horse does not run.

Each-way, priced

Worked example. A horse at 12.00, each-way at a quarter of the odds for three places, 10 each way (20 staked). Wins: win part pays 120, place part pays (12 - 1) / 4 + 1 = 3.75, so 37.50; total return 157.50. Finishes second or third: place part only, 37.50, a small profit on the 20 staked. Finishes fourth: both lose. Extra places, offered on big handicaps, turn a losing fourth into a paid one; they are the most valuable racing promotion there is.

Best odds guaranteed

If you take a price in the morning and the horse starts at a bigger price, a bookmaker offering best odds guaranteed pays the bigger one. Starting prices drift on a third of runners, so the guarantee is worth a real percentage of turnover to any bettor who bets early. Most British and Irish books offer it on UK and Irish racing, often with conditions on the time of the bet; few offer it abroad.

Rule 4

When a horse is withdrawn after you have bet, the market is re-formed and a deduction is taken from your winnings in proportion to the withdrawn horse’s price: a few pence in the pound for an outsider, up to 90 pence for a short favourite. The deduction applies to early prices, not to starting-price bets, and it is the reason a morning price can pay less than it read. The table of deductions is in every operator’s racing rules.

Starting price and early prices

The starting price is the market’s closing consensus and is, over time, an accurate estimate of a horse’s chance; bettors who consistently beat it are winning. Early prices carry more error and more value, and the guarantee removes the downside of taking them. The exchange, meanwhile, trades every horse continuously at prices set by other bettors, usually bigger than any bookmaker’s after commission for horses at 10.00 and above.

Reading a race

Form (recent finishing positions, read with the class of race), the going (soft ground changes everything), the draw (on some tracks a low stall is worth lengths), the trip (distance) and the jockey booking. Handicaps are races where the weight carried is adjusted to equalise chances; the value is in horses improving faster than the handicapper rates them. None of this is quick to learn, and the market contains people who have spent their lives on it.

Where to bet racing

The exchange for prices and for laying; William Hill, bet365 and Betfair’s sportsbook for best odds guaranteed, extra places and streaming; Betway and Unibet for the same in some markets. The international platforms cover racing thinly and without the guarantees. Australia and the United States have their own operators and their own rules, on our country pages.
