LONDON -- Windsor’s Melissa Bishop finished fifth in the women's 800-metres at the world track and field championships on Sunday in London, England.

The 29-year-old standout from the University of Windsor ran a strong time of one minute, 57.68 seconds.

Caster Semenya of South Africa won gold in 1:55.16 while Francine Niyonsaba of Burundi was second and American Ajee Wilson third.

Bishop spoke about her mindset after the race, saying her result came down to a matter of execution. 

"It's hard to process, but I'm happy to be healthy and be here," Bishop told CBC Sports. "I didn't execute my race and I think that sucks to do at a world championship final, but you gotta play your cards and hopefully you don't make the same mistake next time." 

Bishop raced to silver at the 2015 world championships in Beijing, but finished a heartbreaking fourth at last summer's Rio Olympics.

It's Canada's first world championships without a medal since Edmonton in 2001.
