McKoy retired after competing at the 2008 Beijing Olympics. Following a stint coaching high school girl javelin and discus throwers in Georgia, McKoy returned to her hometown of Mandeville to teach at Hydel High School, with plans to open her own school.
In March 2015, McKoy competed in the UWI Track and Field Meet and took first place in the women's javelin with a throw of 49.62 m. This performance has led to considerations of a senior career for McKoy.
