Dina Asher-Smith just wants to go "faster, faster, faster" after becoming the first British woman to break the 100 metres 11-second barrier.
Three years on from carrying boxes of kit into the Olympic Stadium, the 19-year-old had the sell-out crowd in the palm of her hands at this weekend's Anniversary Games.
Asher-Smith returned to the home of London 2012 as the fastest British woman ever, having broken Montell Douglas' seven-year-old 100m record with a time of 11.02 seconds in May.

That naturally led expectation to rise and the teenager did not disappoint, winning her heat in 10.99 seconds - breaking the national record once more to the audible delight of the 50,000-plus crowd.
"10.99, the first British woman under 11 seconds - I am absolutely over the moon," Asher-Smith said with a wide grin.
"It was more than I could have asked for, to not only run the time but here at the Olympic Stadium in front of a home crowd with my family and friends in the audience. It was absolutely just amazing.
"It was very surreal. It was different and weird having people chanting my name and getting really excited, but at the same time it was absolutely heart-warming.
"I do feel like my PB in the heat was 50 per cent due to the crowd, simply because they really, really made me smile and made my adrenaline run. I put that into the race."
It was certainly a day to remember for Asher-Smith and one which will only boost her confidence heading into next month's World Championships.
The 19-year-old was unable to match her record-breaking feat in the final on Saturday, but was pleased to finish fourth with 11.06 in a strong field.
"I've got to make myself stronger and make sure the end of my races are maintained, that I am consistent with my times, but I am happy," Asher-Smith said.
"I have got a lot of work to do before now and Beijing and obviously work to do when I am out there, but I am just happy to have ended this weekend in one piece and smiling."
Asked if another sub-11 performance in Beijing is the goal, she said, smiling: "Another sub-11 would be great.
"Another sub-11 would be great, plus a 200m PB would be great. Just faster, faster, faster - that would be absolutely amazing."
