A US high school student has set a new 100m world youth record with a time of 10.98 seconds at an invitational meet in Seattle.
Candace Hill, 16, ran a time which would have seen her finish seventh in the women's 100m at the 2012 London Olympics.
It is a better time than the British senior women's record of 11.02 seconds set by Dina Asher-Smith in May.
"I just had a feeling this would be a great race. I'm still speechless and in shock about the moment," said Hill.
"It makes me think differently now that I am running a 10.98. That is among the professional times. It just feels incredible and that I have a bright future in front of me. I could go pro at an early age, but who knows?"
Only nine women in the world have run faster than Hill this year, with Olympic champion Shelly-Ann Fraser-Pryce setting the pace at 10.81 seconds.
