Never. Cows never have colosseum in their milk.
They will usually last just as long as a Toyota or Honda.
They lasted different amounts of time, some could have been skirmishes (small battles between small numbers of men) which wouldn't have lasted that long and some could be huge battles with thousands of men which could last days, weeks even months.
There was chariot racing, gladiator fighting, discus throwing, long jump competitions. There was a long list of event, usually held at the Colosseum or Circus Maximus.
the Colosseum was 6 acres wide and 160 ft. tall
about 500 years.
21 battles the last battle is barry (your rivals) dad
