In the Men’s Long Course 400m Individual Medley, the swimmers showcased their extraordinary talents and determination to secure the title of the world’s fastest. Leon Marchand emerged victorious, setting an incredible time of 4:02.50. His performance was marked by remarkable consistency and strength in each stroke.

Marchand’s butterfly splits (25.77s, 28.89s) were outstanding, allowing him to establish an early lead. His swift backstroke splits (31.40s, 30.58s) demonstrated his technical proficiency and maintained his advantage over his competitors. In the breaststroke leg, Marchand displayed endurance and power, evident in his splits (33.87s, 33.77s). As he approached the freestyle leg, his swift transition (29.83s) enabled him to hold on to his lead and secure a well-deserved victory.

Michael Phelps, the legendary swimmer, closely followed Marchand with a time of 4:03.84. Phelps showcased his prowess, particularly in the butterfly (25.73s, 29.19s) and freestyle (28.94s, 27.85s) splits, where he demonstrated his speed and skill. However, his breaststroke (34.77s, 35.79s) splits were relatively slower than Marchand’s, costing him the top spot.

Ryan Lochte, another swimming icon, secured the third position with a time of 4:05.18. Lochte displayed remarkable consistency across his butterfly (25.62s, 29.40s) and backstroke (31.17s, 30.67s) splits, showcasing his technical finesse. However, he faced challenges in the breaststroke (34.18s, 35.49s) and freestyle (29.55s, 29.10s) legs, where he couldn’t match the speed of Marchand and Phelps.

Chase Kalisz, Kosuke Hagino, Laszio Cseh, Carson Foster, and Tyler Clary all exhibited outstanding performances, but they were narrowly outpaced by the top three finishers.
