# Sandro Viana

Sandro Ricardo Rodrigues Viana (born March 26, 1977, in Manaus) is a track and field sprint athlete who competes internationally for Brazil.
Viana represented Brazil at the 2008 Summer Olympics in Beijing. He competed at the 100 metres sprint and placed 6th in his heat without advancing to the second round. He ran the distance in a time of 10.60 seconds. Together with José Carlos Moreira, Vicente de Lima and Bruno de Barros he also competed at the 4x100 metres relay. In their qualification heat they placed fourth behind Trinidad and Tobago, Japan and the Netherlands. Their time of 39.01 was the seventh out of sixteen participating nations in the first round and they qualified for the final. There they sprinted to a time of 38.24 seconds, the fourth time after the Jamaican, Trinidad and Japanese teams. He also took part in the 200 metres individual, finishing fourth in his first round heat, with a time of 20.84 seconds. With 21.07 seconds in the second round he only placed seventh in his heat, which was not enough to qualify for the semi-finals.
At the 2012 Summer Olympics, he again competed in the 200 metres and the men's 4 × 100 m relay. He did not reach beyond the heats in the 200 m and the Brazilian men's 4 × 100 m team missed out on the final by 0.06 of a second.
Viana would retroactively be awarded the bronze medal for the 4 × 100 metres relay at the 2008 Summer Olympics following the demotion in 2017 of the Jamaican team for Nesta Carter's failed anti-doping test.
