The men's C-1 500 metres event was an open-style, individual canoeing event conducted as part of the Canoeing at the 2000 Summer Olympics program.
A semifinal was held on 29 September with the top three finishers advancing to the final.
Kolonics, initially a C-2 canoer, moved to C-1 500 m when he and his partner Csaba Horváth failed to qualify in the Hungarian Olympic trials.
His prior success in this event was a silver at the 1993 world championships, but he was able to upset then two-time defending event world champion Opalev (The Russian has won this event world championship five times as of 2008.)
Before his 2008 death, Kolonics would win two more world championship silvers in the event, earning them in 2001 and 2002.
