This is a window into Late Victorian Society. Most vertebrate species exhibit sexual dimorphism. Fashion dictates how humans display sexual dimorphism. Males sprout abundant facial hair while females have hourglass figures provided by corsets. Male status is higher - the women on horses wear masculine dress with dark colors and high top hats. A major technological limit of horse power is evident in the lap covers worn by both sexes on the carriages. The automobile was initially haled as the solution to a mountainous solid waste problem in cities.
The event could also be seen as a concours d'elegance or rally with fancy carriages and big steeds instead of badges featuring snorting bulls, prancing stallions, and checkered flags.
