Massacand qualified for two swimming events at the 2008 Summer Olympics in Beijing, by clearing FINA B-standard entry times of 55.24 (100 m backstroke) and 2:00.16 (200 m backstroke) from the European Championships in Eindhoven, Netherlands. In the 100 m backstroke, Massacand challenged seven other swimmers on the third heat, including Olympic veterans Derya Büyükuncu of Turkey and Sung Min of South Korea. He finished ahead of Buyukuncu in fifth place and twenty-seventh overall by 0.21 of a second, breaking a Swiss record of 55.21 seconds. In his second event, 200 m backstroke, Massacand knocked off Greece's Dimitrios Chasiotis to last place on the same heat by half a second (0.50) in 2:01.80. His Olympic time in the 200, however, was 1.64 seconds slower than his record set earlier at the European Championships. Massacand failed to advance into the semifinals, as he placed thirty-second overall in the preliminary heats.
