Ali vs. Frazier III — Thrilla in Manila (1975)

A 14-round war in 105°F Philippine humidity that Ali called the closest thing to death he'd ever known, pushing both men beyond human limits before Frazier's trainer stopped it. Over 400 punches were landed, with Ali's volume overcoming Frazier's relentless pressure. This bout outperforms #2 Hagler vs. Hearns in sustained brutality, lasting nearly five times as long without a single lull in action. The fight generated 725 million global viewers, a record that still stands. Ali absorbed Frazier's signature left hook repeatedly, yet his conditioning proved superior to the average championship fight, making this the gold standard for endurance under extreme duress.
