Horse racing betting can look like another language, especially when you land on the Grand National page and see a wall of fractions, place terms, and markets you’ve never heard of.

So, I’m going to walk you through the basics in plain English, and that way, you can have a bet without feeling lost, or at the very least, you will have a much better idea of how the whole process works.

What Betting Odds Really Mean

Odds are simply a way of showing how much you might win and how likely the bookmaker thinks that outcome is.

In UK horse racing betting, you’ll mostly see fractional odds like 5/1, 10/3, or 9/2. The first number is your profit, the second is your stake.

For example, a bet at 5/1 means that you win £5 for every £1 staked, plus your £1 back. Shorter odds like 6/4 or 2/1 mean the horse has, at least on paper, a really great chance of winning.

Conversely, longer odds like 33/1 or 50/1 mean the horse is considered less likely to win, more of a long shot, but the potential payout is bigger should the horse surprise everybody and actually win the race.

You might also see decimal odds on some apps (for example, 6.00 instead of 5/1). This is just a different way of expressing the fractional odds that we are more familiar with in the UK.

They show your total return per £1 stake, including the stake, so you just multiply the stake by the odds: £10 at 6.00 returns £60. Same bet, different way of writing it.

Win and Each-way Bets

For the Grand National, almost everyone starts with a simple win or each-way bet.

A win bet is exactly what it sounds like: your horse has to win the race. If it finishes anywhere else, the bet loses.

An each-way bet is really two bets in one: one part on your horse to win and one part on your horse to place (finish in the places paid by the bookmaker).

Because it’s two bets, a £5 each-way stake costs £10 in total. If your horse wins, you collect on both parts; if it only places, you just collect the place part.

Bookmakers set the place terms. For the Grand National, many firms pay 1/4 or 1/5 of the win odds for several places, often at least four, and sometimes more, as a special offer.

If you find a bookmaker that is paying five places for the 2026 Grand National, it gives you an extra chance of a return if your horse sneaks into the first five rather than having to win outright.

Other Markets You’ll See

Once you scroll past the main win and each-way prices, the markets start to multiply. You don’t have to use any of these, but it helps to know what they are.

Common options include:

  • Place only: Betting on a horse just to finish in the places, with odds adjusted accordingly
  • To finish in the top 4/5/6: Similar idea, especially popular in big handicaps like the National with huge fields
  • Without the favourite: The bookmaker removes the favourite from the result for settlement purposes, so you’re betting on the rest of the field “minus” the hot favourite

On some sites, you’ll also see bets on a horse to be placed in the first 10 in the Grand National or a specific horse to finish the race (handy in a contest where many don’t).

These are all ways of softening the task from “pick the winner of a 34‑runner marathon” to something more manageable.

Forecasts, Tricasts, And The Clever Stuff

If you start to feel confident, or at least mildly optimistic, you may look at forecast and tricast bets.

A forecast is a bet on which horses finish first and second. The classic version is a straight forecast: you name the winner and the runner‑up in the correct order.

Some bookmakers also let you do a reverse forecast, which covers both orders – so if you fancy Horse A and Horse B to fill the first two spots but aren’t sure of the order, you back both combinations, which doubles your stake.

A tricast extends that to first, second, and third in the exact order. These bets can pay very well in big handicaps, but they are tough to land: one horse in the wrong place and the whole thing collapses, a bit like a bad Jenga move.

They’re best treated as fun small-stakes bets rather than your main approach to the Grand National.

How Bookies Build The Market

Odds aren’t plucked from the sky. Bookmakers set an opening market based on their view of each horse’s chance, using form, ratings, trends, and, in the National’s case, stamina and jumping ability.

They use a stack of statistical models and advanced algorithms to create a market that both ensures fairness for you, their customer, and allows them to make a profit.

Once the market is live, prices move as money comes in. If lots of people back a horse, its odds shorten (say from 20/1 into 12/1). If there’s little interest, its odds may drift (from 12/1 out to 25/1).

This is why you sometimes see a horse labelled as an “early plunge” horse in National week – the price has moved significantly because racing fans have latched onto it.

Case in point is at the Cheltenham Festival, Mighty Park in the Supreme Novices Hurdle accounted for 5.4% of total bets made before the racing even began!

Bookmakers also build in a margin (their profit edge) across the whole field, so the total of all implied probabilities usually adds up to more than 100%.

Practical Tips For Grand National Beginners

You don’t need to become a full‑time odds trader to enjoy a bet on the Grand National. A few simple habits go a long way.

Decide your stake first: Pick an amount you’re happy to lose and stick to it.

Start with win or each-way: They are the easiest bets to understand and follow.

Check each-way terms: Extra places can be more valuable than a slightly bigger price, especially at Aintree.

Don’t chase long shots for the sake of it. It’s tempting to go straight to the 66/1 chances, but a solid 14/1 each-way with good place terms can be much more sensible.

Then again, if you just like the name of a horse or however you pick one, the odds won’t make much of a difference.

The National is meant to be an enjoyable puzzle, not a maths exam. If you feel stressed by the markets, you’re probably overcomplicating it.

Think of odds and markets as the menu rather than a test. You don’t have to order everything.

Pick one or two bet types you understand, back a horse you’re comfortable cheering for over four miles and thirty fences, and let the race do the entertaining.
