At the 2012 Summer Olympics in London, Surgeloose competed in both individual and relay swimming events. A year earlier, he posted a FINA B-cut of 1:48.96 (200 m freestyle) from the World Championships in Shanghai, China. In the 200 m freestyle, Surgeloose challenged seven other swimmers on the third heat, including three-time Olympian Tiago Venâncio of Portugal and semifinalist Nimrod Shapira Bar-Or of Israel. He raced to fourth place by six hundredths of a second (0.06) behind Venezuela's Cristian Quintero in his personal textile best of 1:48.77. Surgeloose failed to advance into the semifinals, as he placed twenty-fifth overall in the preliminaries. Surgeloose also placed twelfth as a member of the Belgian team in the 4 × 200 m freestyle relay. Teaming with Pieter Timmers, Dieter Dekoninck, and Louis Croenen, Surgeloose swam the second leg with a split of 1:48.22 to set a Belgian record of 7:14.44 in the heats.
