Sally Pearson's second world championship gold has elevated her to position of the best Australian track athlete of the modern era, says Australia's head coach.
Pearson was considered the main challenger to world record holder Kendra Harrison heading into the event, and with the American putting in a messy performance it was the Australian who took her second world title in a time of 12.59 seconds, adding to the one she won in Daegu back in 2011.
The 2012 Olympic champion won her second world title in 12.59 seconds ahead of American Dawn Harper Nelson (12.63) and Bermany's Pamela Dutkiewicz (12.72).
But the people she wanted to thank first on crossing the line to claim world championships gold in the 100m hurdles were those who had been there every day for the past year and more.
"Far out, that was bloody hard", gasped Pearson, who became only the fourth woman to win the world title a couple of times.
"From the first day I started training (in August 2016) I knew it was possible, I knew I could get here", she said.
"It's been a long journey back from injury, but to get this moment and go and celebrate in front of my family is unreal".
After injury denied Pearson of the opportunity to defend her Olympic crown previous year in Rio, she chose to coach herself.
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.
"Me and Sally have just battled it out for years and it's been so great to be here with her".
"When I knew I felt that I knew it was in me to do it".
She assumed favouritism for the 2017 world title by clocking the fastest semi-final time of 12.53 on Friday evening and carried that dominance into the final.
"I love this stadium".
Nelson, Pearson's long-time rival, was excited to be back and win the silver again in London.
Her next challenge will be winning a third successive Commonwealth title on home soil on the Gold Coast next year. "This is just so incredible to be a world champion again", Pearson, also the silver medallist in the Beijing Olympics, said.
"Silver tastes like gold tonight", she said.
"I don't know if it was surprise or what, but the emotion just escaped my body because I was so excited and so happy to have achieved what I have worked so hard for", Pearson said.
"It's hard to compare eras, I don't think you can, and it would be stupid of me to do that - Betty Cuthbert was a freak".
