The 27-year-old had already been assured of her place in the marathon at the Rio 2016 Paralympic Games and had claimed victories in the women’s T54 100 metres, 800m and 5,000m events on the opening two days of competition.

McFadden continued her domination by clocking a time of 3min 34.84sec to win the women’s T54 1500m, with Chelsea McClammer and Amanda McGrory completing the top three in 3:35.01 and 3:35.06.

Following the victory in the middle distance event, McFadden secured her fifth win by triumphing in the T34/51/52/54 400m event in a time of 54.40sec.

Cheri Madsen and Tatyana’s sister Hannah crossed in second and third respectively in times of 55.79 and 57.37.

The event also saw Cassie Mitchell, who is battling leukaemia, lower the world record in the T51 class by achieving a time of 1:36.44.

Jarryd Wallace narrowly missed out on breaking the T44 100m world record by finishing in a time of 10.71, with his team-mate Richard Browne having previously achieved a time of 10.61 at last year’s World Championships.

Silver was earned by Blake Leeper, who returned from a one-year suspension for cocaine in June, while Jerome Singleton clocked 11.15 to end third.

“The world record is that goal that’s always there in every race, but it’s not something you can focus on,” said Wallace, a two-time world champion.

“It just happens, if you execute the right race at the right time, the time will be there.

"With how I’m running at practice and how I’m putting things together, it’s in the tank.”

Lex Gillette, who has won T11 long jump silver at the last three Paralympic Games, triumphed at the trials with a leap of 6.42 metres.

The local athlete, who was competing in his home state, was followed by Tanner Gers and Gianni Toce after they achieved respective distances of 5.22 and 4.15m.
