Run or Alligator walk race
Select a start position. Select a finish location.
One person does an alligator walk in shallow water.
One person must run, but in deeper water (ideally up to the chest).
Have them race from start to finish location. See who wins.
This game works on gliding, kicking, and teaching the concept that pushing the water isn’t faster than streamline or gliding through the water. If swimmers put their face in the water alligator walking it is a super bonus!
