How Betting on Horses Works

Horse racing is incredibly exciting to watch and bet on, with fast, action-packed races taking place all over the world. In the US, the biggest races are the Kentucky Derby, Preakness Stakes and Belmont Stakes, known as the Triple Crown. You can bet on these big races every year, but there are plenty of other horse racing events on the calendar too.

Betting on horses is just like any other, you select an event and then look at the different options available. First though, it pays to know a little more about the sport and how it works.

How Horse Racing Works

Horse racing is just like any other type of racing. At the beginning of the race, all of the horses are lined up in stalls, which will open up as the race gets underway. Horses are ridden by jockeys, who direct them over any obstacles and towards the finish line as quickly as possible. The winning horse gets the plaudits, but most horse races reward the top three places.

While that’s the basics of it, there are many different types of horse racing, and the rules can vary depending on the event you’re betting on. Before you bet, it’s important to note the nature of the race and the track that’s being used.

Racetracks in the US

Racetrack length and surface type make a big difference in how the horses perform. In addition, tracks can be either steeplechase (with obstacles) or completely flat. In most parts of the world, flat racing is more common, and the US is no different. For example, the Kentucky Derby is run at Churchill Downs, a flat dirt track.

The length of racetracks varies a lot. Distances in the sport are measured in furlongs, which is 660 feet or around 201 meters. Most races are over quickly, coming in at just 10 furlongs. However, there are lots of longer races too, which are typically endurance races rather than sprints.

Bear in mind that if you’re betting on international horse racing, the type of course used can vary considerably. Always check this out before you bet, and factor it in when looking at which horse you should bet on.

Understanding Horse Race Betting Odds

At most horse racing sportsbooks, odds are displayed as fractions rather than the typical format you may be used to. However, it’s still really easy to work out how much you’ll make from your winning bet.

You always divide the first number by the second and then multiply your stake by the result. For example, if you see a horse with odds of 3/1 to win the race, you’d divide 3 by 1, to give you 3. For a $100 stake, you’d win $300 if the horse wins.

On the other hand, for a horse that’s 1/3 to win, you’d divide 1 by 3 to give you 0.33. Here, you’d win $33 if you bet $100, and the hose wins.

Pari-Mutuel Horse Race Betting

While full horse racing betting isn’t legal in every state, a lot of places across the country have pari-mutuel betting instead. This is often offered at horse racetracks, even in states that don’t have legal sports betting.

Often referred to as pool betting, every dollar wagered on a specific market is pooled up. The winners are paid out the total sum of all wagers minus the costs taken by the racetrack.

With pari-mutuel betting, there are no fixed odds before the race starts. This means you have no way to tell what kind of profits you’d make. However, once all bets are off and the race is underway, you’ll be able to calculate your potential payout.

Horse Racing Betting Markets

There are lots of different ways you can bet on horse racing. Typically, these are placed in two separate categories. There are straight bets, which are bets on a single race, and exotics, which tie multiple races or multiple horses into one bet. Here are some examples:

WinReal Men Violin to Win Race 10 at KeenelandA prediction that this particular horse will be the first to cross the finish line and win the race.
PlaceTrademark to PlaceA bet on that particular horse to either finish second or third in the race.

  1. Open your sportsbook app or load the site in your device
  2. Make your first deposit and claim the betting promo
  3. Search for horse racing in the menu or enter a specific race track in the search bar
  4. Choose an event you want to bet on and look through the different horses and markets to bet on
  5. Select a horse to add it to your bet slip, then enter your stake and confirm
  6. Watch the race live to see the results!

Live Horse Racing Betting

Most people bet on horse races before they get underway, but did you know you can bet live too? Most online sportsbooks now have a live betting section where you can get the latest odds on events happening right now. This includes horse races. Depending on the length of the race track, horse races can be over in the blink of an eye or take many minutes to complete.

When horse races are live, you’ll be able to check the latest odds at your online sportsbook. These are updated throughout the race, so expect plenty of volatility as the race progresses. Most betting sites that feature live horse race betting will include live streams of the race or a graphic that shows the positions of the horses as they run down the track.

It’s a lot more convenient and it means you never have to miss out on a betting opportunity. Simply open your phone, log into your account and place your bet.

Strategies for Betting on Horses

Horse races are notoriously difficult to predict, especially when there’s a large field with lots of runners. However, it is possible to make consistent profits from horses if you follow the right strategies and research every bet. Here are some key tips for you:

Look at Form Guides and Trainer History

Horse racing is extremely closely linked to betting, so it’s no surprise that there’s a huge amount of data on every horse and trainer. You can look up form guides to see the recent form of each horse before they compete. Don’t just look at the position they finished, but also the course length and type of track they were racing on. Trainer history is also important, as some trainers have a great reputation for producing winning horses.

Find Value in the Odds

The single most important thing you can do to increase your chances of making consistent profits is to ensure you’re always finding value in the odds. This means getting the best odds at your sportsbook and finding examples of horses that are undervalued. For example, if a horse that’s in great form but hasn’t run on this track before is the clear favorite, you’d get better value by betting on its closest rival instead.

Look for Expert Tips Online

Before a race gets underway, especially if it’s a big event, look out for tips from experts. A lot of horse racing industry experts give free advice and picks for major races, helping bettors choose the best horses. While they don’t get it right every time, tipsters help you narrow down the field and show you which horses will most likely win or upset the odds. Use them together with your own research to make your bets.
