Having won the women’s 200 metres T54 final on Saturday (July 15), the multiple Paralympic and world champion triumphed in the 1,500m and 400m events today.

McFadden had suffered problems with blood clots earlier this year which hampered her training, but she showed no ill-effects as she held off the chasing pack to cross the 1,500m finish line in a Championship record time of 3 min 25.23sec.

A strong finish from Australia’s Madison de Rozario earned her the bronze medal in 3:25.56 with American Amanda McGrory second in 3:25.43.

In the evening session, McFadden clinched the 400m crown in 53.74sec with China’s Zou Lihong second in 54.53 and compatriot Cheri Madsen third in 55.05. 

The 28-year-old will begin her quest for a fourth gold medal tomorrow when she competes in the 800m heats.

"It has been a really good day," McFadden said after her second success.

"It was a really nice night, perfect weather and a really strong competition.

"I was exhausted after the 1,500m, but I tried to have a nap and have some therapy on the legs.

"We do train like this - two sessions in a day - but it's still exhausting and hard on the body.

"I am feeling it tonight and I will sleep well."

Serbia’s Zeljko Dimitrijevic marked his final event before retirement in style by twice smashing the world record on his way to defending the men’s club throw F51 title.

The 46-year-old added more than two metres on to the world record of 29.96m he set en route to victory at the Rio 2016 Paralympic Games, first throwing 31.75m and then 31.99m.

India’s Amit Kumar Kumar won silver with an area record of 30.25m and Serbia’s Milos Mitic, second behind fellow countryman Dimitrijevic at Rio 2016, claimed bronze with a personal best 29.06m.

"This was a very important competition for me because I knew I was going to retire afterwards," Dimitrijevic, who had planned to retire after his London 2012 Paralympic triumph here, before returning to the sport in 2014, said.

"At the Games in 2012 this was my first gold and my first world record in this stadium, so it was my wish to finish my career in the stadium where it all started.

"I can’t describe how it feels to be back here."

Among the other world record breakers today was Great Britain’s Sophie Kamlish in the heats of the women’s 100m T44, an event that saw the 20-year-old go onto seal gold.

Kamlish posted a global mark of 12.90 to reach the final in which she clocked 12.92 to secure her maiden world title.
