Setting up the patterns
Every barrel and pole is measured to its center. The start line runs fence to fence, and the drawing shows the arena from the gate end, with the left side fence at the top.
Cloverleaf barrels
WPRA (2027 rule book) uses the standard 90, 105 and 105 foot triangle with the score line 60 feet from barrels 1 and 2 whenever the arena allows it: at least 70 feet to stop behind the score line, barrels 1 and 2 at least 18 feet from the sides and barrel 3 at least 30 feet from the far end. In a smaller arena WPRA prefers the same triangle with a shorter score line, then a pattern reduced in proportion, with barrel 3 at least 25 feet from the end and at least 50 feet to stop (45 feet only in an extra small arena).
Iowa 4-H starts at 105 feet between barrels 1 and 2, 120 feet to barrel 3 and 75 feet straight out from the timing line to barrels 1 and 2, and takes 15 feet off every distance until it fits. The run from barrel 3 home may come down by less than a full step if there is room to stop. Iowa's sheet gives no fence clearance, so the tool starts at 15 feet as a club value.
Nebraska 4-H uses the same 105 and 120 foot triangle, 15 feet from every fence, reduced 5 yards at a time, though barrel 3 need not come in a whole 5 yards when there is room to stop. Its drawing labels the start line to barrel 1 both 15 yards and 25 yards, so enter the distance your show uses; the tool starts at 45 feet (the 15 yard label) as a club value. The start and finish line is 30 yards long, or 12 feet shorter than barrels 1 to 2 on a smaller course.
Wisconsin 4-H (2026 state rules) sets the pattern to fit: barrels 1 and 2 at most 75 feet apart, barrel 3 at most 150 feet from the start line, no barrel within 15 feet of a fence, and a suggested 30 feet from the timing line to the entrance end. The rules don't say how far barrels 1 and 2 sit from the start line, so the tool starts at 60 feet as a club value.
Pole bending and keyhole
The tool puts the poles and the keyhole on the arena's center line, measured from the start line (the questions below give the sizes). Wisconsin's 2026 Key Race does not say where its 100 feet is measured to, so it is not drawn here.
How penalties and placings work
| Rule book | Knocked barrel | Knocked pole | Ties |
|---|---|---|---|
| WPRA | +5 seconds | No pole event | No rule: share the place |
| Nebraska 4-H | +2 seconds | +2 seconds | Run-off |
| Wisconsin 4-H | +5 seconds | +5 seconds | Run-off |
| Iowa 4-H | Not given: club rule | Not given: club rule | No rule: share the place |
The fastest total wins: time plus penalty seconds. Off pattern, no time and disqualified runs get no place and are listed under the placed riders. WPRA and Wisconsin disqualify a missed or broken pattern; Nebraska gives it the lowest ribbon placing. Nebraska also charges 2 seconds for things like losing a hat or crossing the start line before the gate is closed; type those in Fines.
Example: a Wisconsin 4-H show in a 250 by 130 foot arena
The arena is wide and long enough for the largest Wisconsin pattern: barrels 1 and 2 are 75 feet apart, 27 ft 6 in from the side fences, and barrel 3 is 150 feet past the start line. With the start line 40 feet from the gate and barrels 1 and 2 at the club's 60 feet, barrel 3 ends up 60 feet from the far fence and 97 ft 6 in from each of the other barrels.
In the junior barrels, Mason runs 14.96 and knocks a barrel: 19.96 with the 5 seconds. Ava runs a clean 19.96, so they tie for third and run off. Open this example to see the placings and printouts.
Questions
What are the standard barrel pattern measurements?
WPRA's standard pattern is 90 feet between barrels 1 and 2, 105 feet from each to barrel 3, and 60 feet from the score line to barrels 1 and 2, with at least 70 feet to stop. Nebraska and Iowa 4-H use 105 feet between barrels 1 and 2 and 120 feet to barrel 3.
How do you make a barrel pattern smaller for a small arena?
WPRA first shortens the score line, then shrinks the pattern in proportion, keeping barrels 1 and 2 18 feet from the sides and barrel 3 25 feet from the end. Iowa takes 15 feet off every distance at a time, Nebraska 5 yards off the triangle. Wisconsin 4-H sets it to fit, 15 feet from every fence.
How far apart are the poles in pole bending?
Six poles stand 21 feet apart in a straight line, with the first pole 21 feet from the start line, in the Nebraska, Wisconsin and Iowa 4-H rules. Wisconsin also wants the last pole at least 21 feet from the fence, so the line needs 147 feet beyond the start line.
What are the keyhole race dimensions?
Iowa 4-H uses a 22-foot circle with a 5-foot throat and 5-foot sides, and the center of the circle is 100 feet from the timing line. Other clubs set their own sizes, which you can enter under Club custom.
What is the penalty for knocking over a barrel?
WPRA and Wisconsin 4-H add 5 seconds per barrel (Wisconsin also 5 per pole), and Nebraska 4-H 2 seconds per barrel or pole. Iowa's sheet sets none, so use your club's.
How are ties broken in a timed event?
Nebraska and Wisconsin 4-H run ties off: the winner must ride within 2 seconds of the original time or the run-off is held again. The WPRA and Iowa documents give no tie rule for a single run, so tied riders share the place: 2=, 2=, then 4.
