Helmet Soccer is a paired elimination game.  Usually in a bracket elimination format.  Each rider lines up at one end of the field in their own lane.  A full open face helmet is placed on the field about ten feet ahead of them.  They must advance the helmet by kicking it.  They must not advance the helmet by hitting it with their motorcycle or picking it up in any fashion.  When they kick the helmet across the for end line of the track then they must turn around and kick it back across the start line.  The first helmet across the line is the winner.   

Line judges will be needed between the lanes and at out of bounds.  If a riders object helmet is kicked out of bounds or into the opponents lane then a line judge must run to pick up the helmet and place it in the center of the riders lane even with where it went out of bounds.  It is up to the rider to back up or pull forward to get in position to kick the helmet again.
