Richard Whitehead was one of the stars of London 2012 and is the defending champion in the men’s 200m T42. Whitehead, who broke the world record earlier this year, competes alongside David Henson tonight, while Samantha Kinghorn competes in the T53 400m. World record holder Joanna Butterfield is also a strong medal contender in the women’s F51 club throw.
Over at Lagoa Stadium, rowing finals get underway with four British boats in contending from 13:30 BST. In the women’s AS Single Sculls, Rachel Morris will make her third Paralympic Games appearance, but her first in a boat after transitioning from cycling.
Tom Aggar is the longest-serving member of the GB para-rowing squad, having made his debut in 2007, and also competes in the AS Single Sculls, while Lauren Rowles and Laurence Whiteley go in the mixed TA Double Sculls. In the LTA Coxed Four, GB are aiming to retain the title they won four years ago, with Pam Relph the only crew member returning.
After the men’s triathlon yesterday, it is the turn of the women today down at Copacabana beach. Lauren Steadman has already competed in two Games as a swimmer, but has now made the switch to triathlon where she competes in the PT4 category with Faye McClelland and Clare Cunningham.
Having crashed out of the recent World Championships in Rotterdam, Steadman will be looking to put things right in Rio, while Alison Patrick and Melissa Reid, each with world titles to their names, will hope to dominate the PT5 category.
In track cycling Neil Fachie, also known as “The Power Monkey”, will compete for gold in the B 1000m time trial with pilot Pete Mitchell, and Lora Turnham and pilot Corinne Hall, who picked up a bronze medal at the 2016 Para-cycling Track World Championships, have the B 3km Pursuit.
In the C1-5 Team Sprint, Jody Cundy, Jon-Allan Butterworth and Louis Rolfe, who between them already have a gold and bronze medal from Rio, will be looking to get the better of China and Spain after missing out on gold in London four years ago.
And finally, there are also appearances for six-time Paralympic gold medallist David Weir in the men’s 400m T54 heats, and ParalympicsGB flagbearer and equestrian rider Lee Pearson begins his Rio campaign today.
