Canadian wheelchair racer Michelle Stilwell claimed her second gold medal at the Rio Paralympics on Saturday, winning the women's 100-metre event.

The 42-year-old from Parksville, B.C., beat American Kelly Morgan and Belgium's Marieke Vervoort to take top spot in 19.42 seconds, which is a new Paralympic record.

Stilwell, who also holds the world record in the 100, now has six career Paralympic gold medals. She won her first race of the Games a week ago in the 400.

Stilwell is only the second female Paralympian to have won gold in two separate summer sports, having been part of Canada's gold-medal winning wheelchair basketball team in Sydney. Complications to her spinal cord injury forced her to switch to track after the Games in 2000.

Stilwell isn't sure what her immediate racing future holds, but she's learned to approach every race like it's her last.

"I do that every time, because you never know," Stilwell said. "And I think that's really what it's about for everyone. No matter if you're Paralympian or able-bodied, you can have a life-changing injury.

"In an instant your life changes. And so I think I try and enjoy every moment. And have fun."
