Career
Gushchina represented Russia at the 2008 Summer Olympics in Beijing competing at the 4x100 metres relay, together with Aleksandra Fedoriva, Yuliya Chermoshanskaya and Yevgeniya Polyakova. In their first round heat they placed second behind Jamaica, but in front of Germany and China. Their time of 42.87 seconds was also the second time overall out of sixteen participating nations.
With this result they qualified for the final in which they sprinted to 42.31 seconds, the first place and the gold medal.
Belgium and Nigeria took the other medals. The Jamaican team did not finish due to a mistake in the baton exchange.
