Roping can be done either singly or in
a team of two.
When done singly, a horse and rider are lined up in a box, with a calf in another box. The
calf is let loose, and the horse chases. The rider must throw his rope around the calf's neck,
then wrap it around the saddle horn. He then jumps off, runs up to the calf, throws it to the
ground and must tie up three legs in a particular knot. The horse must keep the rope taught so
the calf cannot escape.
In team roping, there are two riders. One is called a header, and must throw a rope around the
calf's head. The other is called a heeler, and must lasso one of the calf's back feet while it is
running.
The runs are judged by time. Riders can be
disqualified if they miss, if they do not tie three legs, or if they break from their starting box
too soon.
Horses must have cow sense, which means they must have natural talent in working with cattle.
In addition, they must be able to gallop from a stop, turn, stop quickly, and work on their
own without a rider.
Most roping horses are quarter horses, paints, or crosses.
