It earns Peaty his third Olympic gold medal
Britain won another thrilling gold in the pool as they set a mixed 4x100m relay world record. Kathleen Dawson, Adam Peaty, James Guy and Anna Hopkin won an absorbing race which took some interpreting as to who was in the lead when men and women raced against one another in an entertaining contest.
It earns Peaty his third Olympic gold medal after winning the 100m breaststroke title in Rio and earlier this week in Tokyo.
The quartet of Dawson, Peaty, Guy and Freya Anderson were more than two seconds clear of the rest of the field in the heats, setting a new European record, and Team GB eased to victory on Saturday morning.
Anna Hopkin replaced Anderson for the final freestyle leg here and touched out in three minutes and 37.58 seconds for Britain’s fourth gold in the pool at Tokyo 2020 and seventh gong overall – matching their tally from London 1908.
The time was 0.83 seconds better than the previous best benchmark of 3mins and 38.41ecs – set by China last year – while they finished 1.28secs clear of China, with Australia taking bronze.
This event has been added to the Olympics schedule for the first time – where two males and two females must be selected but the nation can use any combination in the backstroke, breaststroke, butterfly and freestyle splits.
It means the lead can change hands multiple times as men and women can race against each other in the same leg of an event that was first introduced for long course swimming at the 2015 World Championship.
Dawson started with the backstroke and her time of 58.8s meant Peaty leapt into the pool with Britain sixth, and the 100m breaststroke gold medallist’s astonishing split of 56.78s helped them up into fourth.
Guy, who won his first gold earlier this week in the men’s 4x200m freestyle relay, clocked exactly 50s in the butterfly to take Britain into the lead and Hopkin finished in 52s flat to spark exuberant celebrations.
