Setting Standard Barrel Pattern from Montana WPRA 6/09 k At least 25 feet to back fence © 2009 Kitty Herrin for montanawpra.com 105 Feet use 300-foot tapes Barrel pattern Center from gate Box eyes 210 Feet n At least 18 feet to fence 150 Feet 260 Feet 300 Feet (0’ and 300’ ends of tape here) 60 Feet At least 18 feet to side fence l 0 Feet 8f 10 210 Feet r n. i t. 2 Scoreline E Ma ye rke r 300 Feet (0’ and 300’ ends of tape here) At least 60 feet from scoreline to back fence 130 Feet Center Gate or Back of Arena if Side Gate For the minimum stopping room: If right barrel is at 0’, center of gate is 130’ and left barrel is 260’ then it’s 62 feet from scoreline to a straight back fence. When possible allow more stopping room, just make sure that it’s the same distance from center of gate to both the right and left barrels, then measure from eye straight back to fence to determine distance. Use 300-foot tape to mark the pattern. Measure a triangle with the sides equal distance from barrels 1 to 3 and barrels 2 to 3 (105 feet in a standard pattern). It’s 90-feet from barrel 1 to barrel 2 in a standard pattern. Make sure the 3rd barrel is at least 25 feet off the back fence and the 1st and 2nd barrels at least 18 feet off side fences (barrels 1 and 2 may be different distances off the side fences, depending on how the arena is set up). Before setting barrel stakes, use a second 300-foot tape to V the 1st and 2nd barrels with the center of the gate if running from the gate (if there is a side gate V the 1st and 2nd barrels from the center of the pattern off the back fence). Shift the barrel pattern accordingly. See calculations above to ensure at least 60 feet of stopping room—measure from eye straight to back fence to verify calculations. All this is done to ensure that a rider going either right or left has the same advantage. Use the second tape to box the eyes. Measure from 1st barrel to 2nd barrel, to the left eye marker, to the right eye marker, and back to 1st barrel forming a box. The distance between the barrels and their respective eyes should be the same (example: if it’s 60 feet from barrel 1 to the eye it should be 60 feet from barrel 2 to the eye). Then measure the diagonal from barrel 2 to the opposite electric eye and barrel 1 to the opposite electric eye. These diagonals must be the same. Diagonals are figured by using the following equation: A×A+B×B=√C [electric eye to the 1st barrel (A), 1st barrel to 2nd barrel (B), diagonal from eye to 1st barrel and eye to 2nd barrel (C)]. For a standard pattern with a 60-foot score line here’s the equation: 60×60 (a) + 90×90 (b) [3600+8100] = √11700 108 ft. 2 in. (c). For a pattern with a 45-foot score line here’s the equation: 45×45 (a) + 90×90 (b) [2025+8100] = √10125 100 ft. 7.5 in.
