ASAP after the race of their finishing time and place. There is no reason to wait until the very last runner is across the finish line before beginning the tabulation of results. Do not draw out awards ceremonies with numerous announcements, prize drawings, or awaiting the results of other races, fun races, etc . Begin the awards ceremony ASAP after the race. If there are other races, announce those results in the order that they are run.
Prize drawings can take place after the awards ceremony.
Every runner should receive a time and place. Manual back up should be provided if chronomex or other electronic or computer timing is used. Race Directors should provide a person to insure that runners do not pass other runners in the chute after crossing the finish line. The finish line should be clearly marked by line or tape on the pavement and where possible by banner. A long chute is recommended to prevent runner stack ups in larger races.
