[6][7] In his final event, 1500 m freestyle, Ivanov participated in the same heat against Czech Republic's Vlastimil Burda and Chinese Taipei's Li Yun-lun.

Before the start of the program's longest race, Ivanov was cast out of the field for a "no false-start" rule, leaving Burda and Li as the only two men standing.
