Laura Muir warned her rivals, insisting she was more dangerous than ever.
The 29-year-old opens her fifth world championship fight in the 1500m races in Eugene on Friday.
Muir is aiming for a first medal at the World Championships after finishing fourth in London five years ago and fifth in Doha in 2019.
She was struggling with foot and calf injuries leading up to her last two championships but feels like she’s established herself after last summer’s Olympic silver medal in the 1500m.
“We’ve done it now and that takes the pressure off a bit and makes me more dangerous,” said the Scot, who finished fifth in Beijing in 2015 and reached the 800m semifinals two years earlier.
“I don’t have that much weight on my shoulders. I can go out and be more relaxed. When I’m relaxed, I run better.
“It’s nice to go in and not have that pressure on me knowing you have to get that medal or we’ve never won a global outdoor medal. I don’t have to prove myself.
“In Doha it was the second fastest time I’ve ever run, including in a championship final. It was incredibly frustrating to set one of the fastest times ever and I wasn’t even fourth but fifth.
“It was after an injury, so what could I have done if I hadn’t had an injury? That was the most significant I’ve had in my career.
“If anything, it highlighted a few areas where I was weak and other than that we worked really hard to make that weakness much stronger. I don’t know if I would have been as fast, strong and robust for the Olympics without the injury.
“It was a bitter pill to swallow but I am now physically fitter and stronger than I ever would have been.
“Hopefully I can add the elusive World Cup medal this year, lucky for the fifth time.”
Still, Muir has yet to defeat Kenyan Faith Kipyegon, who beat her to Olympic gold in Japan last year and hasn’t lost since Tokyo.
“Male or female, she’s the best 1500-meter sprinter this world has ever seen,” Muir said. “She’s been to every single World Cup since 2015, maybe 2013 and has won a medal almost every time, as well as two consecutive Olympics and having a child.
“She’s an amazing, amazing athlete and it’s an honor to run alongside her even though she’s very, very fast.”
The Oregon Championships begin a busy summer for Muir, who will also represent Scotland at the Commonwealth Games ahead of the European Championships in Munich in August.
“Even a championship medal is huge,” said Muir, who was looking to defend her 2018 European 1500m title. “Who knows, but to win a medal in all three within a short period of time would be crazy. That would be great.
“That’s what I set out to do at the beginning of the year – to compete in all championships and win a medal in all three.
“I just have to try not to get too carried away thinking about it right now and focus on one championship at a time.”
Muir will be joined in the heats by Katie Snowden and Melissa Courtney-Bryant, while Reece Prescod and Zharnel Hughes will run in the 100m heats.

The 4x400m mixed relay also has a chance to win Britain’s first medal with the heats and final on opening day at Hayward Field.
