Triple Crown betting: three races in five weeks

The Triple Crown is winning the Kentucky Derby, Preakness and Belmont Stakes in one year. Only 13 horses have done it, most recently Justify in 2018. Each race is bet in pari-mutuel pools, and some books price a sweep.

The Belmont has been run at Saratoga, at a shorter distance, while Belmont Park is rebuilt; the Preakness is also moving during Pimlico work. Check the current year.

Why the sweep is so hard

The three races test different things. The Derby has up to 20 starters and a rough start. The Preakness has a smaller field but comes just two weeks later. The Belmont is traditionally run at 1½ miles, longer than most of these horses have ever raced.

Fresh horses are a big threat. Many trainers skip the Derby or the Preakness to target a later leg, so a Triple Crown hopeful often faces rested rivals in the Belmont.

Between Affirmed in 1978 and American Pharoah in 2015, 13 horses won the first two legs but did not complete the sweep. That gap of 37 years shows how hard the final step is.

Ways to bet

Each race has win, place and show pools and exotic bets like exactas, trifectas and superfectas. These are pari-mutuel, so odds come from the money bet and lock only at post time.

Churchill Downs runs future wagers on the Derby months ahead, with odds fixed when you bet. Some licensed sportsbooks in states that allow it list fixed odds on whether a horse will win the Triple Crown once it has won the Derby.

Multi-race bets link the legs within one card, like the Pick 4 or Pick 5 on Derby day. There is no standard pari-mutuel bet that links all three Triple Crown races.

Pricing a sweep

Suppose a Derby winner is a 60% chance in the Preakness and a 45% chance in the Belmont. The chance of a sweep is 0.60 × 0.45, or 27%, before any book margin. Fair odds would be about +270.

Fixed odds offered after the Derby are often shorter than that, because public money loves a Triple Crown story. Doing the math helps you see whether a price is fair or just exciting.

Once the Preakness is won, the Belmont odds on the hopeful are often very short. Many bettors look at exotic tickets with other horses on top instead.

After the 90 seconds

Questions before and after you play

A 90-second guide cannot cover every table moment. Tap a group, then a question — answers are short paragraphs, not one-liners.

01Basics

What is the Triple Crown?

Winning the Kentucky Derby, Preakness Stakes and Belmont Stakes in the same year, a feat only 13 horses have managed.

Who was the last Triple Crown winner?

Justify in 2018, three years after American Pharoah ended a 37-year wait in 2015.

How far apart are the races?

Usually two weeks from the Derby to the Preakness and three more weeks to the Belmont.

02Bets

Can I bet on a horse winning the Triple Crown?

Some licensed sportsbooks offer fixed odds on a sweep, usually after the Derby, where state rules allow it.

Are Triple Crown races pari-mutuel?

Yes. Bets at tracks and race books go into pools, and the odds lock only when the race starts.

Is there one bet linking all three races?

No standard pari-mutuel bet links all three, so most people bet each race on its own.

03Strategy

Why do so many fail in the Belmont?

The race is long and rested rivals that skipped earlier legs often beat a tired favorite.

How do I price a sweep?

Multiply your chances for each remaining race, then compare that with the odds offered.
