The vice-principal of South Park Elementary, Strong Woman, announced her intention to compete in the annual Strong Woman competition during a school assembly. However, on the day of the competition, she encounters another athlete named Heather Swanson who looks very muscular, and had recently identified as a female two weeks ago. Heather Swanson unexpectedly breezes through every event, eventually clinching first place, with Strong Woman coming in second.
The event is held in an athletics stadium with small seating galleries on all four sides. In additional to the standard track and field courses, other sports featured in the competition include boxing, weightlifting, tire flipping, arm wrestling and tug-of-war.
