Kemasuode represented Nigeria at the 2008 Summer Olympics in Beijing, competing at the 4 x 100 metres relay together with Agnes Osazuwa, Oludamola Osayomi and Ene Franca Idoko. In their first round heat they placed fourth behind Belgium, Great Britain and Brazil. Their time of 43.43 seconds was the best non-directly qualifying time and the sixth time overall out of sixteen participating nations. With this result they qualified for the final, in which they replaced Osazuwa with Halimat Ismaila. They sprinted to a time of 43.04 seconds, a third place and a bronze medal after Russia and Belgium.[1] In 2016, the Russian team was disqualified and stripped of their gold medal due to doping violations by one of the Russian runners, Yuliya Chermoshanskaya, thereby promoting Nigeria to the silver medal position.[2]
Kemasuode failed a drugs test at the Circuito de Corridas e Caminhada in Brazil and was banned from competition for two years over the period of 24 July 2009 – 23 July 2011.[3]
