Retaining his T44 100m title from London, the 23-year-old provided a sprinting spectacle, taking Britain’s medal total to 27, including 12 golds.
Peacock, who has had somewhat of a troubled Rio preparation, showcased his ability to rise to the big occasion finishing in a time of 10.81 seconds, ahead of New Zealand’s Liam Malon.
In the velodrome that saw so much British success at the Olympic games, cyclist Sophie Thornhill – with pilot Helen Scott – won the women’s B 1,000m time trial, whilst Jody Cundy made up for disappointment in London, with gold in the c4-5 1km.
Over at the Olympic Stadium, Georgie Hermitage, Sophie Hahn and Libby Clegg won gold in their respective 100m athletics finals.
Hermitage set a world record of 13.13 seconds to win her T37 title, before Hahn won her T38 final in 12.62 seconds.
It was something of a dramatic day for Clegg, who was reinstated after being disqualified in the morning heats. Brazil had made a complaint against Clegg, claiming that her guide runner had been in an illegal position during the morning heats. Clegg went on to win the T11 100m final, setting a new world record en route.
Ellie Robinson, 15, claimed victory in the pool, setting a Paralympic record and winning the women’s 50m butterfly S6 in 35.58 seconds, while Steph Slater picked up a silver medal in the women’s 100m butterfly S8.
Stef Reid and Ali Jawad added silver medals from the long jump and powerlifting respectively, while powerlifter Zoe Newson, club thrower Gemma Prescott and swimmers Susannah Rodgers and Lewis White took bronze.
