And she added: “I don’t think my motivation is going to go down because of that [Olympic medal]. If anything, it’s going to go up. Now I’ve got nothing to lose.
“It’s given me an awful lot of confidence as an athlete to know that I’ve been there and done it. I’m just so pleased that I was able to go out there and get that medal last year. It does take a lot of pressure off myself.”
Muir, the 2018 European champion, has twice finished fifth in the world 1500m final and took silver in the event at the 2018 World Indoor Championships.
And she believes the 1500m in Oregon will be “incredibly competitive”.
“It could potentially be more competitive than what the Olympic final was last year,” she told BBC Scotland.
“It makes that achievement even better when you can get a medal because it is so competitive.
“I’m in a really good spot – very, very happy with how things have been going. If I’m running well, I’m very chilled.”
