TEHRAN, April 23 - Traditionally the first event of the Heavyweight program, this was originally a smooth stone from the river bed, sometimes shaped by a local mason.
The stones used to vary greatly in shape and weight, particularly those used for tests of strength, where stones up to two hundred and sixty five pounds in weight were used.
Now the stone is either sixteen pounds or twenty two pounds. The weight is putt, delivered, with one hand only from in front of the shoulders. A run not exceeding seven feet six inches from the trig is allowed.
