Horse racing is a unique spectacle and we all know betting and odds also play a huge role in the sport of horse racing. Betting on horse racing is the ultimate when it comes to having a view and backing that up by putting your well-earned cash down. Horse racing punters and bookmakers have been around for years and with the digital age now in full swing, lockdown times, the way people place bets has certainly changed.
The Grand National odds for each of the Grand National runners 2021 are listed on this page using our odds comparison. The best odds for your grand national horse will be displayed here, using the latest best odds from the bookmakers.
The amount which the grand national odds vary changes as we approach the race, with betting odds being fairly stable in the days before but changing rapidly on the day of the race, especially as we reach the start time.
When selecting your horse, don’t just focus on the runners with the shortest odds. In recent years we have seen some winners come home with big grand national odds. See our tips for The Grand National 2021 here.
Once you have made your selection for the Grand National you need to decide what type of Grand National bet you want to place. Do you want to play it safe and back your selection each-way or are you feeling especially confident and want to back your Grand National horse with a win-bet only?
As well as using the best odds to decide which bookmaker to bet with, you may also want to consider which bookmakers offer you a free bet or special offer for opening an account with them. See our Grand National Free bets page.
When looking at Grand National odds, it is important not to immediately be drawn to the shortest odds runner in the market – whilst it might be favourite, the odds might not reflect its actual chance to win the race.
It is important to survey the field, look at each runner and look out for signs like recent form, trainer form, jockey form and previous record on course.

While odds are quite literally the hard numbers of betting, making the best of them is more art than science. Getting the best odds about your selections depends on several factors, including your own approach to betting and the types of horses you tend to back. As such, any advice that can be given has been earned from years of personal experience and your sweet spot will only be found through similar means.
Accordingly, it is always a good idea to watch markets and how they develop wherever possible. Keep an eye on the markets the evening before the race and compare to the odds on the day, especially market movers on the exchanges. As with anything in racing, the lessons drawn are all the better if you are familiar with the horses involved. That said, many of the factors in reading the markets boil down to reading the humans involved – to paraphrase a quote so beloved by horsemen, the horse cannot affect what price it is.
If bookies are offering prices now, what is in it for them? If someone wants to get a wedge on, when would they do it? What signs might be there that today is ‘The Day’, when it is all fancied to come together on another day? Judging the odds market is something that even the best bettors get wrong more often than other factors. You will back a few that go off five times the price and are never involved. The satisfaction of being an early adopter more than makes up for these moments, though, and even though it stings to see your 8-1 bet get chinned eight hours later as 15-8 favourite at the festival, the fact you read the market so deftly soon comes along as a bit of an anaesthetic.
When looking at the odds (price) of a horse, the two formats used are decimals and fractions. Betting exchanges operate in decimals, whereas fixed-odds betting firms generally operate in fractions. In contrast, the decimal format factors in the initial stake. Betting odds of 4/1 would equate to 5.0 in decimal terms, 5/1 would be 6.0, and so forth.
Each race has a favourite. This is the horse most likely to win, which is reflected in having the shortest price displayed with betting operators. You will see an F alongside the horse’s odds when they are the favourite. If more than one horse has the same odds of winning according to the betting market, this will be displayed as JF, meaning joint-favourite.
All betting markets for a bookmaker have to have an ‘over-round’ percentage. This percentage is how the bookies make their money. If the market percentage is 100%, based on the odds on all the runners, the bookmaker should break-even on that event. Anything under 100% means you could back EVERY horse in that race and make a small profit. Due to the number of bookmakers around, competition is fierce. Finding races that are under 100% is not as hard as they used to be – generally smaller fields. In the Grand National with 40+ runners, the over-round percentage is always more like 125-150% Anything over 100% and this is the potential profit that bookmaker can make on that race. They need to make money, but also keep their prices competitive. If the over-round is 120%, the bookmaker would expect to pay out £100 for every £120 he takes in on bets – this is how they make money.
When determining the returns of a fractional bet, the second number always suggests the stake and the first number denotes what the profit will be if the bet wins. Take 4/1 as an example. If you stake £1 on a horse, then you stand to win £4 if the selection wins the race, which excludes your initial stake. In spoken form this is “Four-to-one” and sometimes this can be written as: 4-1. Odds are just maths. To illustrate some examples, let’s call each number a unit. So: 4/1: For every 1 unit you stake, you will receive 4 units if you win (plus your stake) 7/2: For every 2 units you stake, you will receive 7 units if you win (plus your stake) 9/4: For every 4 units you stake, you will receive 9 units if you win (plus your stake) If you see fractional odds the other way round – such as 1/4 – this is called odds-on and means the horse in question is a hot favourite to win the race. In spoken form this is “Four-to-one on”. 1/4: For every 4 units you stake, you will receive 1 unit if you win (plus your stake) 1/2: For every 2 units you stake, you will receive 1 unit if you win (plus your stake) Sometimes you will see Evens or EVS displayed. This is the equivalent of a 1/1 fraction. Again it means the horse in question is expected to win the race. EVS: For every 1 unit you stake, you will receive 1 unit if you win (plus your stake)
There are a few things that decide the odds on each Grand National horse. In the build-up, most bookmakers will have similar prices on each horse. Prior to the final runners being declared (2 days before the race) the bookmakers will have what is called an ‘ante-post’ market. This is filled with all the horses that the bookmakers think will ‘potentially’ run in the Grand National. Due to safety reasons, the maximum number of runners in the Grand National is 40. Therefore, there will be a lot of marked-up horses that will not race. Each bookmaker will be competing for punters by offering competitive Grand National odds. However, this doesn’t mean bookmakers can just make up odds and prices for the horses. If a horse is being well-supported (a lot of money placed on it) their hands might be forced. They have to offer lower Grand National odds in their ante-post market than a competitor. In simple terms – the more money placed on an individual horse then the shorter their odds will become. While the opposite to this is that if there is no interest in a certain horse the odds for that runner may well increase.
Odds are the return you can expect to get if the horse you bet on is successful. It reflects the amount of money bet on a horse; the more money that is invested, the shorter the odds. When horse racing odds are shown in the form of 7-2, 5-1, etc, it expresses the amount of profit to the amount invested.
The favourite to win the Grand National changes throughout the course of the year, mainly due to performances at other racetracks. The ante-post market is available all year round, but tends to take more shape once the list of Grand National entries is published in late-January. Major races that may affect the betting include the Becher Chase at Aintree in December, the Grand National Trial at Haydock in February, and the Grand NationalGold Cup in March.
The average odds of a winning Grand National horse are around 20/1 – while 23 of the last 29 Grand National winners returned a double-figure price. Seven winners had minimum of four runs before going on to win the Aintree Grand National. The only three who had less in recent years were Ballabriggs in 2011, One For Arthur in 2017 and Tiger Roll in 2019 with only 3 runs each.
Until recently, it was commonly assumed that horses carrying over 11 stone never win. This allowed punters to rule out a decent slice of the entrants. However, this trend is showing signs of reversal in recent years. Not least in 2015 when Many Clouds carried the monster weight of 11st 9lb to victory, while since 2009 we’ve had six Grand National winners carry 11st or more in weight.
Famous bookies such as William Hill, Paddy Power, Betfair and bet365 are just a small sample of the big bookmakers that punters will look to at the time of the Grand National and you can’t go wrong with one of these respected firms.
Nearer the time these bookmakers will have dedicated 2021 Grand National offers, so it’s important to keep an eye out. Also you can take advantage of Grand National Free Bets on our Free Bets page. Ultimately, the experience of placing a Grand National bet online is exactly the same, no matter the bookmaker.
Bookmakers don’t like to take lots of bets on one horse, because if that horse wins the bookmaker will lose money. The bookmaker will offer more attractive (bigger) odds on other horses in an effort to get people to back those instead. Sometimes this actually works in favour of the punter as with The Grand National, only a few favourites have ever won.
Ultimately, all bookmakers will aim to make a profit regardless of the outcome of the race and that’s why you will see the odds fluctuating right until the horses start racing.
The appeal, for many people, is that the Grand National has produced winners from non-favourites. Some of these unlikely winners have returned odds of 100/1 notably Mon Mome in 2009 and famously Foinavon back in 1967.
In the last 100 hundred years only 12 favourites have won the Grand National. Six of them have come in the last 20 years: Tiger Roll (2019), Don’t Push It (2010), Comply Or Die (2008), Hedgehunter (2005), Earth Summit (1998) and Rough Quest in 1996.
In addition to picking a winner or having an each-way bet on any particular horse, there are many other special markets that bookmakers will offer punters. These other forms of Grand National betting can be called "fun" or "special bets" and bookmakers will give different odds for these. Below is a list of some other forms of betting you can do for the Grand National:
- How many horses will finish the race
- Odds on all horses to jump the first fence
- Odds on UK or Irish trained winner
The amount of special bets can differ with each bookmaker. Therefore, it is worth shopping around to find something that will interest you.
