Australian para-athletics star Isis Holt has won her second-straight T35 100m world title in London.
Teenage sensation Isis Holt has defended her T35 100m world title in record time at the para-athletics championships in London.
The 16-year-old Australian ran 13.43 seconds in the final on Wednesday, eclipsing her previous world record by 0.14 seconds to take the gold medal.
The performance surpassed her own expectations after recently recovering from a bout of tonsillitis.
"I wasn't even sure if I'd be here in London, so to be able to come out here and run a time like that, I can't get over that," Holt said.
"It's added to my resilience as an athlete. Knowing that I can pull up and get results like that gives me confidence for the future."
It continues a stellar meet for Holt, who also won a second straight 200m title three days earlier.
Australian's Brianna Coop and Carly Salmon placed fourth and sixth respectively behind Holt in Wednesday's final.
Meanwhile, Australian shot putter Claire Keefer won a silver medal in the F41 class, while Jaryd Clifford won bronze in the T13 1500m.
Wheelchair racing veteran Angie Ballard failed to defender her 400m T53 world title, finishing fourth in the final.
Australia sits sixth on the medal tally after the seventh day with five gold, seven silver and six bronze medals, with China leading with 17 gold.
