Dame Sarah Storey clinched her 12th Paralympic title on a golden opening day of the XV Games in Rio for Great Britain.
ParalympicsGB won five gold medals - three in track cycling and two in swimming - plus three silvers and three bronze medals for a total of 11 from day one.
Here's what else you missed overnight ...
Dame Sarah Storey was unusually emotional
Her 12th Paralympic title took Storey past Baroness Tanni Grey-Thompson as Britain's most successful female Paralympian. The 38-year-old, in her seventh Games, won the C5 three-kilometres individual pursuit as team-mate Crystal Lane took silver.
Storey cried on the podium after claiming her first Paralympic title as a mum. Her daughter Louisa is three and congratulated Storey by telling her of grazes suffered in a fall earlier in the day.
The honour of Britain's first medal of the Games went to Megan Giglia
She claimed gold in the C1-2-3 3km individual pursuit, three-and-a-half years after a brain haemorrhage. After Storey's win, Steve Bate and his tandem pilot Adam Duggleby won the 4km pursuit title. The success saw Britain claim three gold medals in 70 minutes on the cycling track.
Ollie Hynd led the way in the pool with victory in the S8 400m freestyle
He claimed the title his brother Sam won in 2008 and which proved elusive when he took silver at London 2012.
Hynd clocked a world record in "inspiring" the British team, according to Bethany Firth, who claimed gold herself in the S14 100m backstroke on a night when Brazil's Daniel Dias claimed his 11th Paralympic gold in front of a partisan crowd. Firth won the same event as a 16-year-old for Ireland before switching allegiance.
And everything else from the swimming ...
Jonathan Fox had to settle for silver in defence of the S7 100m backstroke title he won at London 2012, and Harriet Lee took silver in the SB9 100m breaststroke.
Stephanie Millward took bronze in the S8 400m freestyle, Jessica-Jane Applegate was third behind Firth and Andrew Mullen claimed third in the S5 200m freestyle behind Dias.
But Britain must wait until day two for a first athletics medal.
Jonnie Peacock will be looking to defend his T44 100m title in arguably the Games' blue riband event as he qualified quickest for the T44 100m final.
Britain's seven-a-side footballers lost 2-1 to Brazil, the women's wheelchair basketball squad lost to Canada, but the men beat Algeria.
