Ladies' barrel racing is the only ladies' event in professional rodeo. The contestant must cross the scoreline and run a clover-leaf pattern around three barrels and back across the scoreline to end time.
Either barrel, on the left or right, may be taken first, but a contestant will be disqualified for not following the clover leaf pattern.
A five second penalty will be added to the run time for each barrel knocked down, but a contestant may, from a riding position, hold a barrel from falling.
The time is generally taken with the use of an electric eye to the hundredths of a second.
