Heather Jameson has placed seventh in her T37 200m heat.
The Irishwoman, running in heat one, ran 32.76. The position means she won't reach the final.
Germany's Maria Seifert won the race in 29.87.
Jameson commented: "It was below my best today, but I am happy to have personal bests and Irish records in two out of three events. I cannot wait for Rio in four years."
