Crystal Emmanuel made her Olympic debut at London 2012 where she made it to the semifinals of the 200m. She has been one of Canada’s top sprinters over the last few years. At the 2011 Canadian Championships she became the first woman to win both the 100m and 200m since 2003. In 2012 she won the 200m and was second in the 100m. In 2013, she reversed her results, winning the 100m and finishing second in the 200m. She replicated those results in 2014. Emmanuel ran the lead-off leg for the 4x100m relay at the 2013 IAAF World Championships where Canada finished sixth in national record time of 42.99 seconds. She led off again at the 2015 IAAF World Relays where Canada finished fourth, setting another national record of 42.85 seconds and qualifying Canada for the 4x100m relay at Rio 2016.
