Team Roping competition begins with a steer in a chute and ropers on horseback to either side. A run begins with the steer being released from the chute and given a head start down the arena (known as the barrier distance, about 10-15 feet), after which point the ropers may give chase. The first roper (the header), comes up on the steer's left side and, throwing his loop, ropes the steer around the horns or neck. Next, the header secures the steer by wrapping the rope remaining in his hand around the saddle-horn (called dallying). After making his dallies, the header will then steer his horse to the left across the arena, pulling the steer behind him.
It will now be the job of his partner (the heeler) to follow with the steer, approach from behind, and skillfully throw his loop so that it encircles both of the steer's hind feet. The heeler will finish the run by stopping his horse while simultaneously dallying his rope around his saddle-horn.
Time is called by an arena judge (the flag-man or flagger) who waits until both ropes are taut and each ropers' horse is facing the steer. At that instant, he will drop his flag, signaling the timekeeper to stop the clock and record the team's time. Penalties can be added to the team's total elapsed time; if a team begins chasing before the steer has traveled the length of his allotted head start (called breaking the barrier or breaking-out) ten extra seconds will be added to the team's time. If the heeler is able to rope only one hind foot, the penalty is five seconds. And, of course, if either roper misses his target, the team receives no score for the run (a no-time).
