Australia’s Rheed McCracken broke his own men’s 100 metres T34 world record on his way to claiming victory at the World Para Athletics Grand Prix in Nottwil today.

The 21-year-old sped out of the blocks and quickly took control at the front, coming home in 14.80sec at the Swiss Paraplegic Centre.

It took 0.12 seconds off the previous mark he set in nearby town Arbon last year.

"You know I really surprised myself actually with that one," the Paralympic and world silver medallist said.

"I was hoping to go fast today but I wasn’t really expecting that to be honest.

"After the 200m yesterday I kind of felt that there was an opportunity to go quick here in the 100m and I woke up feeling really good.

"As soon as the gun went I felt comfortable in the first 15 pushes."

Canada’s Austin Smeenk finished second in 15.71, while the United Arab Emirates’ Mohamed Alhammadi came third in 15.83.

There was also a world record set today in the men’s 100m T51 as Paralympic and world champion Peter Genyn of Belgium knocked 0.34 seconds off his own mark, crossing the line in 20.07.

Taking second place was London 2012 Paralympic gold medallist Toni Piispanen, who held the world record for three years prior to Genyn breaking it earlier this month.

The Finn finished in 20.80, while Great Britain’s Stephen Osborne came third in 22.61.

The afternoon session saw Australia’s Madison de Rozario equal the world record in the women’s 1,500m T53/54.

De Rozario has been in terrific form this year, winning double Commonwealth Games gold as well as the London Marathon, and she added to her women's 800m T53 win yesterday with a superb victory in the 1,500m T54.

Racing in a breakaway pack which included American duo Tatyana McFadden and Susannah Scaroni as well as home favourite Manuela Schaer, De Rozario underlined her world-class credentials as she crossed the line first in 3:13.27.

It equalled McFadden’s world record set in Arbon in 2015.

Schaer came through for second place, clocking a European record of 3:14.10 in the process.

Scaroni finished third in 3:14.32.

In the men’s 1,500m T33, Britain’s Martin Pistorius set a European record by clocking a time of 4:25.84.

Five-time Paralympic champion Hannah Cockroft of Britain, meanwhile, notched up her third win in two days, pushing hard with her head tucked distinctively low to take a convincing win in the women’s 100m T34 in 17.60.

The Netherlands’ Amy Siemons finished second in 18.88, while Australia’s Robyn Lambird came third in 19.82.

World and Paralympic champion Marcel Hug of Switzerland delighted the home crowd as he claimed victory in the final heat of the men’s 1,500m T54 in the afternoon session.

Hug was up against a tough field and he was made to work hard with the United States’ impressive young talent Daniel Romanchuk taking up the pace at the gun, just like he had done a day earlier in the 800m.

But with one lap to go Hug had secured the inside lane and with Romanchuk racing wide, he looked in control.

Sure enough, the "Silver Bullet" found another gear with 200m remaining, holding off his rivals to cross the line first in 2:57.77.

Canadian world record holder Brent Lakatos came through for second place in 2:58.11, while Romanchuk finished third in 2:58.12.

Among the winners in the field was Paralympic champion Mauricio Valencia of Colombia in the men’s javelin F34 with 34.70m.

Compatriot Diego Fernando Meneses Medina ranked second with 33.76m, while Morocco’s Azeddine Nouiri came third with 26.63m.

Thailand’s Sakchai Yimbanchang won the men’s javelin F57 with 40.53m followed by Turkey’s Musa Davulcu with 29.39m and Czech Republic’s Premysl Liska with 19.06m.

Action in Nottwil is due to conclude tomorrow.
