Carline Muir

In 2016 Muir moved to UK based coach Nick Dakin where, along with winning a number European races she broke her 8 year old Personal Best, running 51.05 in Madrid. After winning the Canadian National Championships 400m she was officially named to Canada's Olympic team in the individual Women's 400m and then as part of the 4 × 400 m Women's relay for the second time. The Women's 4 × 400 m finished 4th at the Rio Olympics.

Muir currently resides in Toronto, Ontario. Between 2012 and 2014 she trained in Florida before moving back to Toronto to train and the Athletics Canada East Hub, where she helped the Canadian 4 × 400 m Women's Relay team finish 6th giving automatic qualifying for the 2015 World Championships and Rio Olympics 2016.

At the 2010 Commonwealth Games in Delhi, India, Muir missed out of the medal podium, as she placed sixth in the final by more than two seconds behind her former rival Montsho in the 400 metres. She initially finished fourth for her national team in the women's 4 × 400 m relay; however, they were immediately upgraded into the bronze medal position, following the disqualification of the Nigerian team.

At the 2009 Summer Universiade in Belgrade, Serbia, Muir captured the bronze medal in the women's 400 metres, finishing behind her teammate Esther Akinsulie by thirty-seven hundredths of a second (0.37), with a time of 52.07 seconds. She also displayed a spectacular performance by pacing the women's 4×400-metre relay team to a gold medal triumph.

Muir became the youngest track and field athlete to represent Canada at the 2008 Summer Olympics in Beijing, where she competed for the women's 400 metres. She ran in the second heat against six other athletes, including Italy's Libania Grenot and Botswana's promising track star Amantle Montsho. She finished the race in third place by one hundredth of a second ahead of Cuba's Indira Terrero, with her personal best time of 51.55 seconds. Muir advanced into the next round of the competition, as she secured the final mandatory qualifying slot in the second heat. Muir, however, fell short in her bid for the final, as she placed seventh in the semifinal rounds, with her slowest possible time of 52.37 seconds.

Muir made her international debut at the 2005 Pan American Junior Championships in Windsor, Ontario, where she captured the silver medal for the 400 metres, with an impressive time of 52.38 seconds. She also achieved a top-ten finish for the relay team at the 2007 Pan American Games in Rio de Janeiro, Brazil, and had won two individual silver medals at the national trials. In 2008, Muir set her personal best, and attained a B-standard time of 51.77 seconds at the Harry Jerome International Track Classic in Burnaby, British Columbia, which earned her a qualifying spot for the Olympics.
