Every fundraiser is different and that goes the same for your Awards Ceremony. The more awards you hand out, the longer it will take. Think about timing and scheduling when you decide how you will distribute awards, medals and goodie bags.
Awards can be based on dollars raised, laps completed or race times. Since it is a fundraiser, most groups will recognize participants that exceed their fundraising goals.
When announcing awards and closing your event, a public address system or bullhorn will help your announcements be heard over the crowd noise.
Thank all the participants; you may want to list the names of everyone who made their goal. Recognize top achievers. Share with the group the overall success of your event.
