REGATA DI CARRIOLE ( Wheel Barrow Parade) Probably one of those wild Carnival entertainment opposed to the gondolas parades and the big Canal Grande boat procession, with the Doge leading it all. No masks, simple clothes, servant's hat. My wild guess is that the Wheel Barrow Parade was probably an ironic, lower classes joking competition, just for having fun, and attracting all the public's attention.
