Saudi Arabian sprinter Kariman Abduljadayel made history by being the first woman from Saudi Arabia to compete in the 100m sprint event at the Olympics.
The 22-year-old, dressed in a full-body suit and hijab, was unable to qualify, finishing seventh in her preliminary heat in a time of 14.61 seconds.
However her participation earned widespread praise on social media.
The Saudi sprinter was one of two women to wear the hijab and full body suit for the event.
Afghanistan's Kamia Yousufi came last in her event, finishing in 14.02 seconds.
Their attire was designed to comply with religious laws requiring that women preserve their dignity, however it was designed to give them the freedom of movement required while running.

#Olympics Kariman Abuljadayel is the first. Maybe Saudi Arabia will let more women train and maybe win sprinting events.

Middle distance runner Sarah Attar was the first female track athlete to run for Saudi Arabia at the 2012 London Olympics.
Aged 19 at the time, she wore full clothing and a hijab as she finished last in her 800m heat in London, in a time of 44.95 seconds in London - more than 43 seconds behind heat winner Janeth Jepkosgei Busienei of Kenya.
Attar is due to compete in the women's marathon on Sunday.
Another Saudi Arabian, Wojdan Ali Seraj Abdulrahim Shahrkhani, competed without a hijab in the judo competition in London, at the age of 16.
The Saudi governement lifted their ban on women competing at the Olympics in 2012.
Allowing women to participate in the Games shows that slow changes that are taking place in the country.
In December, women were allowed to vote for the first time and the country is considering removing the ban on allowing women to drive.
