ATHLETICS NEWS - But the Scot has known for some years that Australia's Gold Coast would not be on her horizon in 2018.
Muir, from Milnathort near Kinross, is in the last year of her veterinary studies at the University of Glasgow, with her final exams in May.
Despite senior Scottish athletics officials voicing hopes she might change her mind, the 24-year-old is adamant she is sticking to her original plan.
"It was a decision that was made a good few years ago that I knew I wasn't going to be running there," Muir told BBC Scotland.
"It wasn't going to work out with my final year of vet medicine, my finals in May and placements all the way up to the end of April.
"It will be difficult not to be there. You want to race as much as you can.
"I think if it was a little bit closer you might be able to get away with it, but Australia is a little bit difficult so no, I'm afraid it's kind of set in stone that I'm not doing it."
If anyone thinks Muir is putting athletics on the back-burner though, after a highly successful 2017, they should think again.
