A coordinated effort of horse and rider against time, this event is similar to traditional calf roping except that the cowgirls do not have to throw and tie the calf after catching it. As in calf roping, speed is the main component in this event.

While the roper and her horse wait in the box for the barrier rope to drop, the calf is given a running start. If the contestant leaves too soon the barrier is broken and she receives a 10 second penalty. The cowgirl rides out, ropes the calf, using a 25-foot lariat. She pulls her slack, pitches it out, and brings her mount to a stop. The lariat is secured with an easily broken piece of string that allows it to “break away” from the horn when the calf reaches the end of the rope, and time is called. A piece of colored cloth is attached to the end of the rope to assist the judges in seeing and timing the break.

A cowgirl will receive no time should she break the rope from the horn by hand, or touch the rope or string after the catch is made. The only "legal" catch in the breakaway is around the calf's neck; all other catches receive a no time. The cowgirl remains mounted during the entire process.

This is a fast paced, explosive event with the best ropers on the fastest horses excelling. If you are going to watch breakaway roping, don't blink or you might miss it.
