The longest distance swum by a human in 24 hours is 139.8 kilometers (86.5 miles), achieved by Serbian swimmer Veljko Rogošić in 2006. This remarkable feat took place in open water and showcased extraordinary endurance and stamina. Rogošić's achievement has since set the benchmark for long-distance swimming challenges.
