How Barrel Racing Divisions Work: 1D, 2D, 3D and 4D Explained
The AP Barrel Co. Team · November 1, 2026
If a barrel race flyer says "4D" or "5D," it is using the division format common at open barrel races and jackpots. It is the reason a rider on a green horse and a rider on a seasoned pro horse can enter the same race and both have a realistic shot at a check.
What the D Means
The D stands for division. A 4D race pays four divisions and a 5D race pays five. Everyone enters the same race and runs the same pattern. Riders do not sign up for a particular division; when the race is over, every clean time is ranked from fastest to slowest, and the fastest time of the day sets the line for every division below it.
The National Barrel Horse Association rulebook spells this out. The fastest time in the class sets the 1D. The 2D begins at the fastest time plus one-half second, the 3D at plus one second, the 4D at plus one and one-half seconds, and the 5D at plus two seconds. Because the lines move with the fastest run, the same time might land in the 1D at one race and the 3D at the next.
How the Splits Work
The half-second split is the most common, but it is not the only option. NBHA's payout rules allow a 3D race with one-second splits, a 4D race with either half-second splits all the way down or splits of one-half, one-half and then one full second, and a 5D race that must use half-second splits between all divisions. NBHA also notes that points are always awarded in a 5D format, even when a show pays in 3D or 4D, and that the show's director chooses which payout format to use.
Here is how a common one-half, one-half, one-second 4D split plays out. If the fastest run of the day is a 15.01, the 1D covers times from 15.01 up to the 2D line. The 2D starts at 15.51, the 3D at 16.01 and the 4D at 17.01. If nobody runs exactly on a line, the division goes to the next slower time. A rider who stops the clock at a 16.05 would be competing in the 3D in that example.
The NBHA rulebook does not say what happens when a time lands exactly on a split line, so if that question matters to you, ask the show secretary or producer before you run.
How the Money Divides
At an NBHA show, the jackpotted entry fees are divided among the divisions by percentage. Under NBHA's original option, a 4D race pays 35 percent to the 1D, 30 percent to the 2D, 20 percent to the 3D and 15 percent to the 4D. A 5D race pays 30, 25, 20, 15 and 10 percent. Added money is divided either in the same ratio as entry fees or evenly among all divisions.
Within each division, the number of places paid depends on how many entries the race draws, following NBHA's payout charts. A few other rules are worth knowing. All prize money must be paid out. Prize money is not paid to a contestant who knocks over a barrel. And if no riders qualify in a division, that division's money is divided among the winners in the other divisions.
NBHA Classes
NBHA shows commonly offer more than one class, each run as its own D race. The rulebook defines Open as all ages, Youth as 12 and under as of January 1 of the competition year, Teen as 13 through 18 as of January 1, and Senior as 50 and over as of the date of the show. Riders may enter more than one class.
How BBR Is Different
Better Barrel Races sanctions shows that are put on by independent producers. Under BBR's rules, the number of divisions and the splits used to determine payout are left to the producer, who must advertise them. That means two BBR-approved races can be set up differently, so the flyer matters.
BBR requires that 100 percent of advertised added money be paid as prize money, along with at least 70 percent of entry fees. Places paid and payoff percentages are also up to the producer but must be posted or included in the event rules. BBR's rules suggest a 4D split of 35, 30, 20 and 15 percent and a 5D split of 30, 25, 20, 15 and 10 percent.
For year-end standings, BBR awards points in five divisions using half-second intervals for the first four divisions and a full one-second interval for the fifth. Runs with penalties, or runs more than three seconds slower than the winning time, do not earn points. A member keeps points only from the division where they have the highest standing, and membership must be current at the time of the run to earn points or finals qualification credit.
Rodeo Versus Jackpot
A barrel race at a rodeo usually works differently. In most rodeos only the fastest group of riders gets paid, with no division split. That is why a newer rider may find more opportunity at a divisional jackpot than at a rodeo.
What It Means for a Newer Rider
Before you enter a local jackpot, read the flyer closely. Look for the number of divisions, the split, the payout percentages and the number of places paid. Check which classes are offered and whether you are old enough or young enough for Youth, Teen or Senior.
If you want your runs to count toward standings or finals, find out which association the race is sanctioned by and make sure your membership is current before you run. Finally, focus on clean runs. A tipped barrel takes you out of the money, and a clean, steady run in the 3D or 4D can pay.
Rules and payout charts change, so always check the current rulebook for the association you are running under and confirm details with the show secretary.
