Tie-down roping is a solo timed event. Rope the calf, dismount, flank it, tie three legs with a pigging string. Everything in under 10 seconds if you want to place.
The roper rides out of the box when the calf crosses the barrier. He throws a loop around the calf's neck. The moment the rope is tight, he dallies to the saddle horn (or the horse knows to stop and back). The roper dismounts running, sprints down his rope to the calf, flips the calf on its side, pulls a pre-cut pigging string from his teeth, wraps any three legs, and ties a half-hitch, the knot the judge checks.
Then he throws his hands in the air. Clock stops. The calf must stay tied for six seconds after he remounts and gives slack in the rope. If the knot holds, it's a legal time.
Penalties are brutal. Breaking the barrier: 10 seconds. Calf gets loose: no time. Too slow to dismount or tie: out of the money. Tie-down rewards speed and confidence. The best ropers make the whole run look like one motion.
