For track events, there are several possible scenarios for rounds. For events which are not run entirely in lanes (usually individual events over 800 meters or 880 yards), there are normally 1 or 2 rounds depending on the number of entries. If there are 2 rounds, then the first is called the preliminary round and the second is called the final round. For running events which are run entirely in lanes, there may be from 1 to 4 rounds. One round means timed finals only, 2 rounds means preliminaries and finals, 3 rounds means preliminaries, semi-finals, and finals, and 4 rounds means preliminaries, quarter finals, semi-finals, and finals.
