Which term denotes a full race in chariot racing events?

The term that denotes a full race in chariot racing events is "missus." In the context of ancient Roman chariot racing, a "missus" refers specifically to a complete lap or the entire course that the chariots would race around. Races often consisted of multiple laps, and the culmination of these laps would be termed as a missus, indicating the performance of the teams in the race.

The other terms have specific meanings but do not refer to the full race itself. "Carceres" refers to the starting gates for the chariots, from which they are released at the beginning of a race. "Spina" is the barrier that runs down the center of the racing track, often adorned with statues and other decorations, which the chariots would race around. "Metae" are the turning posts located at each end of the spina that the chariots must navigate around during the race. Thus, while all the terms are associated with chariot racing, "missus" is the one that signifies an entire race.
