In his final Olympic race, Michael Phelps swam the butterfly leg of the men's 4x100m medley relay to secure a 23rd career gold medal. The United States won in an Olympic-record time of 3:27.95, eclipsing the previous mark by 1.39 seconds.
One last turn, one last surge
The Americans held a commanding lead after the first leg, where Ryan Murphy set a world backstroke record of 51.85. But the race turned sharply on the second hundred metres. Great Britain's Adam Peaty, the breaststroke world record holder, overtook Cody Miller and sent James Guy into the water ahead of Phelps.
Phelps entered the butterfly leg trailing by 0.61 seconds. On the return lap, he powered through the water with a windmill stroke, pulled clear of Guy, and handed Nathan Adrian a 0.41‑second lead.
Adrian pulled away on the freestyle and the contest was over. Great Britain took silver in 3:39.24, and Australia claimed bronze in 3:39.93.
A record book written across five Olympiads
The relay gold was Phelps's fifth of the Rio Games, bringing his 2016 haul to five golds and one silver. It followed a rare defeat the previous night, when Joseph Schooling beat him in the 100m butterfly final.
No other Olympian holds more than nine gold medals. With 28 medals overall, Phelps stands ten clear of any other athlete in history.
"It's not the end of a career. It's the beginning of a new journey," Phelps told NBC after the race. "I'm really looking forward to that."
The men's victory arrived minutes after the women's medley relay delivered the United States its 1,000th Olympic gold medal at the Summer Games — an evening where one era closed and another quietly passed.
