Dame Sarah Storey became the most decorated British female Paralympian after claiming her 12th gold medal.
Swimmer-turned-cyclist Storey at her seventh Games surpassed the medal haul of former wheelchair racer Baroness Tanni Grey-Thompson on Thursday night.
It was a dominant victory for Storey in the C5 three-kilometres individual pursuit on the opening day of the Games over GB team-mate Crystal Lane.
The Disley star had already set a world record time in qualifying in 3:31.394 - more than 17 seconds quicker than Lane.
In the final she overtook Lane before the halfway point to claim gold.
Lane, appearing in her second Paralympics, won her first medal with silver.
“Gold medal number 12. I never thought that was possible,” said Storey, who won her first two golds as a swimmer at the 1992 Games in Barcelona.
“After London everyone expected I might retire. Then I had a baby and everyone definitely thought I was going to retire.
“I’ve gone faster today. The gap to my opposition is bigger. I didn’t expect that at all.”
