Sally Pearson, now 30 years old, has won the 100m hurdles final at the world athletics championships in London.
"From the first day I started training (in August 2016) I knew it was possible, I knew I could get here", she said.
She controlled the race from there, winning in 12.59 seconds ahead of long-time rival Dawn-Harper Nelson (12.63).
Favourite Kendra Harrison, who set the world record in the London Stadium previous year having missed out on Olympic selection, again clattered too many barriers as she did in the semis and finished fourth in 12.74.

Harrison faded to finish fourth.
"I've worked so hard, I don't know what has just happened out there".
"(Silver in) 2008 was a surprise, in a way that was just pure excitement", Pearson said. London (2012) was such a relief more than anything, to get it done.
"I'm still young, this was my first world final, people forget that because I'm the world record holder", said the 24-year-old.

"At the end, I could see Sally had won and I thought "it's me and Sally again".
Making the victory even more special was that Pearson had coached herself for the past year.
"On the first day of athletics at the Olympics I made a decision to coach myself", she said.
Pearson looked tense and focused before the race, not acknowledging the crowd when her name was called, but was hugely impressive quickly overhauling early leader Jamaican champion Megan Simmonds and opening a sizeable lead.

Former men's 110m hurdles world record holder Colin Jackson described the Australian's technique as "absolutely flawless" and that, combined with her famed winning mentality and now a body again able to match her mind, took her over the line.
