400 metres Freestyle, Men

Date	24 – 25 July 2021
Status	Olympic
Location	Olympic Aquatics Centre, 2-1, 2chome, Tatsumi, Koto-ku, Tatsumi-no-Mori Seaside Park, Tokyo, Japan
Participants	36 from 31 countries

There was no clear favorite in the 400 free in the absence of China’s Sun Yang, who was out after a doping disqualification. The heats saw both Australians, Jack McLoughlin and Elijah Winnington, and both Americans, Kieran Smith and Jake Mitchell, qualify comfortably. The last qualifier was Tunisia’s Ahmed Hafnaoui, who set a personal best to get into the final.

Winnington led for the first 150 metres when McLoughlin took over and led through 350 metres of the final. However, out in lane eight, Hafnaoui moved into second at 150 metres and stayed there through 350 metres, when he picked it up and gradually moved past McLoughlin for one of the biggest upsets of the Tokyo Olympics in swimming, as Hafnaoui won gold in 3:43.36, a PR by over two seconds, with McLoughlin taking silver, and Kieran Smith coming on for bronze.

Hafnaoui’s gold medal was the second in the pool for Tunisia after Oussama Mellouli’s gold in the 1,500 freestyle at the 2008 Beijing Olympics – Mellouli also won gold in open water swimming at the 2012 London Olympics. For Hafnaoui gold came in the first major international meet of his career.
