Ledecky, 19, broke her own world record to clinch her fourth gold medal of Rio 2016 as she blew away the rest of the competition with a time of 8:04:79 – an astonishing 12 seconds ahead of her nearest challenger. She becomes just the second woman to complete a clean sweep the 200, 400 and 800m freestyles events having defended the title she won at London 2012 when she was just 15.

With the gold medal forgone conclusion from a very early stage, Carlin provided her own impressive performance to see off the challenge Hungary's Boglarka Kapas and seal second place with 8:16:17.

The 25-year-old wins her second medal of Rio 2016, having also claimed silver in the 400m freestyle.

Carlin told BBC One: "Two silver medals, it is an incredible feeling. I'm finally believing in myself and stick to the race plan. I need to go on holiday somewhere. I'm just going to have some time away from the pool."

Elsewhere, 21-year-old Briton Ben Proud claimed fourth place in a hugely competitive 50m freestyle final won by Anthony Ervin of the United States.
