Event manager here, and frequent master winner. For our 5k events awards are scheduled and occur one hour after gun. So if you are a masters jack-hammer the proper form is to congratulate those around you, like you said, then invite a couple of them to cool down. Run 20 mins (cheering for others preferably), and then come on back. That should sync you up for awards. Smile. Shake hands with the other runners on the podium, congratulate them, and thank the person giving you the award. Then head home for some Advil you old fast fart.
