In track cycling, Jody Cundy, competing in his sixth Games, is hoping to bounce back with another gold after a disappointing London 2012. Cundy rides in the individual C4-5 1km time trial alongside teammate Jon-Allan Butterworth. In the women's individual B 1km time trial, Commonwealth champion Sophie Thornhill and pilot Helen Scott aim to overcome a surprise defeat to Australia at this year's Worlds.
All eyes will be on London 2012 champion Jonnie Peacock as he takes on American Jarryd Wallace and Brazil’s Alan Oliveira in the men's 100m T44 final. In the women's 100m, Libby Clegg, who has been reclassified and now lines up with a blindfold, goes head to head with Brazilian crowd favourite Terezinha Guillhermina in the T11. Also competing are Georgina Hermitage in the T37 and Sophie Hahn T38, while double Paralympic Games medallist Stef Reid, who has overcome a back injury, and Gemma Prescott compete in the women's long jump T44 and women's club throw F32 respectively.
Stephanie Slater was inspired to take up Paralympic sport after volunteering at London 2012; today she competes in her first event at Rio 2016, the S8 100m butterfly. Fifteen-year-old Ellie Robinson also took inspiration from London 2012 after watching now team-mate Ellie Simmonds compete. She now strives for her own gold in the S6 50m butterfly, but faces stern competition from world and Paralympic champion Oksana Khrul.
The rowing, which begins at the Lagoa Stadium, is one of three other sports kicking off with their first competition action of the Games alongside judo and wheelchair tennis.Numerous Brits, including Alfie Hewitt and Andy Lapthorne, are in wheelchair tennis action while Jonathan Drane faces Sharif Khalilov in the preliminary round of 16 in the men’s -81kg in the judo with Rachel Morris and Tom Aggar going in the singles sculls.
In powerlifting, London 2012 bronze medallist Zoe Newson competes in the -45kg category, and after finishing fourth at London 2012, world champion powerlifter Ali Jawad goes for the podium in the -59kg category. Shooting continues with Stuart Nangle, who finished fifth against able-bodied rivals in at the Glasgow Commonwealth Games, making his Paralympic debut in the 10m air pistol event.
