How it works

  1. Enter before the day

    Entries are made and paid ahead of time, and there are no day-of entries. Each event page says how to enter, and when entries close.

  2. Run up to three times

    One hound at a time down the 200-yard straight, timed by electric eyes at the start and the finish.

  3. Your best time goes on the record

    The fastest of the three counts, and it stays on the ZASSC record for good: standings, track records and your dog's own page.
