Chad Perris wants to race on until the Los Angeles Paralympics, despite the agony of missing out on a Paralympic podium finish in the T13 100 metres by 0.005secs.

Perris placed fourth with a time of 10.80(.799) in Paris on Sunday, local time, but he was denied a bronze medal by Japan's Shuta Kawakami, who ran a time of 10.80(.794).

Earlier in the day, and on the other side of Paris at the National Velodrome, Perris's younger brother Kane came fourth in the Men's B 1,000m time trial.

The run of near misses was clearly still raw for the senior Perris brother, but 32-year-old Chad, who won bronze in Rio, insists he wants to keep racing.

"Five-thousands of a second or something like that … I probably need to do a little more bench press so my chest can get over the line earlier," Perris said.

"In local races (that's happened) but this is three majors in a row where I've come fourth (by narrow margins).

"It's tough, and being so close every time, it's killing me.

"I know that it hurts when you come in off the track immediately.

"This makes me hungry for more, honestly, it gives you the hunger to run as fast as possible and to try to win medals… 2019 was my last podium and I want to taste a medal again."

Perris had finished second in his heat to raise hopes and his final time set a new Australian record.

While that was of little consolation, a catch-up with his younger brother should go some way to taking away the pain.

"I'm looking forward to sharing a beer with him (Kane) and reflecting on what we've been doing here," Perris said.

"We both came fourth and wanted more, but at the end of the day we're at a Paralympic Games, it's his debut and my third, and hopefully not my last."
