World champion over 200 metres Dafne Schippers wants to use the event at Rio 2016 as redemption after injury hampered her efforts in the 100m.
Schippers finished seventh in Saturday's 100m final as Elaine Thompson, Tori Bowie and Shelly-Ann Fraser-Pryce took the medals.
The Dutchwoman won silver at the Worlds over that distance before beating the likes of Thompson and Veronica Campbell-Brown to gold in the 200m.
And, having been prepared to give up her Olympic dreams due to being hampered by muscular issues, Schippers is now determined to turn her Games around after comfortably winning her 200m heat on Monday.
"Last Wednesday I was ready to go home because of the injury. But I carried on," she said.
"All I could do was to run and have treatment. I was very disappointed that I wasn't able to show what I'm capable of doing. On Friday it was a case of let's see what happens. I was watching it hour by hour. I didn't have too much coordination.
"I was broken. I didn't come here to finish fifth but that was the maximum I could do."
"I'm happy now. I'm much better. I'm glad it went so well in the 200. I've now got the chance to show what I am capable of doing."
