The distance, in boxing, refers to the full number of rounds in a match. It is frequently used in the expression "going the distance", which means fighting a full bout without being knocked out.[1]
In title fights, this is called "the championship distance", which once was 15 rounds but today usually means 12 rounds (See history section),[2] though there were some ten-round championship matches. Non-title fights can be of any length under 12 rounds but are typically 10 rounds or fewer. Women's championship boxing is ten rounds or fewer, each round lasting 2 minutes instead of 3 for men.
