You have two teams of say ten people each. Each team holds hands, facing outwards forming a circle.
Before trying to read the long blathering attempt at an explanation, just look at the video. If viewed from overhead, the notches in the tire treads each represent a person, the road in the video represents
the line they race along.
Each team has one person in contact with a line running down the field forming the visual of a wheel on a street when looking downwards at them. The teams run such that these wheels "roll" along that line requiring each team member to run sideways, backwards and forwards in a circular motion, very confusing and hard to do, which is the point.
Just getting to "roll" slowly would be hard enough.
See the video to get the idea. Each tread notch in the tire represents a person, the road represents the line.
Other than the very hard to do geometry involved, it's a race like any other. First team across the finish line wins.
This would be played on a standard sport field If there were no lines each team could just follow the edge of the field.
To be clear, judges would blow the whistle if for instance the persons representing the contact point with the road (line) weren't lined up perfectly just like a wheel would be on a road.
Just occurred to me, might need to lines so you could verify the wheels stay round. Don't wanna to a tank tread thing.
