Team Penning is three riders, a pen set up at one end of the arena with 30 head of cattle at the other end of the arena. The cattle will be wearing numbers typically 0-9 with there being 3 number 1, three number 2, etc. Clock starts when the first rider crosses the line. The objective is to pull the three cattle wearing the correct number and put them into the pen in the shortest amount of time. Time limit depends upon the class, but is usually 60 seconds for the higher numbered classes. A 30 second time is a good time but you may need to be in the 20s to win.
Team sorting is again three riders but typically the arena is split in half with an opening in the center. There are 10-12 head of cattle wearing numbers agin typically 0-9, if 12 head then two will not have numbers. The objective is to sort the cattle in the correct numerical order through the opening in the fastest time. Common time limit is 75 seconds with a time in the 40s being a good time.
There is also Ranch Sorting which is two riders sorting in a 60ft round pen instead of half of an arena.
