South African sprinter Ilse Hayes became the world's fastest female para-athlete on Thursday (23 April) running the 100m T13 in 11.89 seconds at the IPC Athletics Grand Prix in Sao Paulo, Brazil.
Running with a tailwind of 1.6m/s in the morning's heats, the 29-year-old knocked 0.1 off the previous T13 record set in November 2011 by Cuba's Omara Durand. Hayes' time was also 0.02 faster than the T12 world record held by China's Guohua Zhou, who was previously the world's fastest female para-athlete.
It was not all bad for Durand however who now runs in the T12 class. The 23-year-old ran 12.07 to break the five-year-old Americas 100m T12 record by 0.3.
Just days after running with Olympic sprint king Usain Bolt, Brazil's Terezinha Guilhermina came within touching distance of breaking her own 100m T11 world record set at London 2012. The 36-year-old three-time Paralympic champion ran 12.05, just 0.04 seconds outside her previous best.
In addition to Hayes' world record, four Americas records fell on the track on Thursday with two Brazilians leading the way in the 100m. Tascitha Oliveria Cruz (14.66) broke the T36 record and Ana Claudia Maria Da Silver (16.27) set a new mark in the T42 class.
Venezuela's Yescarly Medina ran 14.62 in the morning's 100m T37 heats to break the America's record, which had stood since 2007, but lost out in the final later to teammate Berliana Castellano (15.04).
Alan Fonteles Oliveira, who will be aiming to retain three world titles at October's IPC Athletics World Championships in Doha, Qatar, made his long awaited return to the track with an impressive 11.00 over 100m.
The fastest time of the day however was set by Brazil's Petrucio Ferreira dos Santos in the final of the men's 100m T47. His time of 10.88 was just 0.07 outside of his own world record set last November and ensured he beat a quality field, which included teammate and 200m world champion Yohansson Nascimento (11.35), who could only manage third.
The much-awaited battle of the Brazilian men in the 100m T11 saw Felipe da Souza Gomes (11.37) edge out world champion Lucas Prado (11.40) to take the win.
Elsewhere there were 100m wins for Brazil's Adriele de Moraes (14.21) in the women's T20; South Africa's Jonathan Ntutu (11.39) in the men's T12; Brazil's Gustavo Henrique Faria Araujo (11.19) in the men's T13; Argentina's Diego Martin Gonzalez (13.76) in the men's T35 and teammate Rotondo Henrique (13.05) in the men's T36; South Africa's Dyan Buis (11.68) in the men's T38 and Sweden's Niklas Almers (14.74) in the men's T54.

In the field events, a number of long-standing Americas records were smashed by Brazilian athletes.
Sandro Varelo de Oliveria saved his best until the final round of the men's discus F55, throwing 32.24m, to break the America's record previously set in September 2006 by 0.83m.
A fourth round effort of 13.20m by Mauro Evaristo de Sousa in the men's shot put F42 beat the previous regional record set in June 2007 by 0.72m.
The men's shot put F12 was a thrilling affair with the Americas record falling four times. In the opening round, Argentina's Antonio Victoriano Rodas threw 10.95m to add 0.95m to the previous best set in Sao Paulo last year.
