Longest UFC fights ever

What counts. Elapsed time is derived from the round the bout ended in, the clock at that moment, and how long each round of that format was booked for — so an open-format bout is measured by its real length rather than as though every round were five minutes. Ties. 96 of the rows below share the same 25 minutes, and 307 bouts on the whole record do. Where two bouts share a value the older one is listed first — the first fight to reach a mark is the one that reached it. 9 bouts excluded. 9 bouts carry a clock that cannot be right — a decision whose recorded end time is short of the round it was scored in, which makes both the round time and the fight length wrong. They are left out of this ranking rather than listed on a number we cannot stand behind. Check us. Every row links the bout’s own page, which carries the official round, clock time and method this ranking was built from.
