Competition format
Slalom canoeing uses a three-round format, with heats, semifinal, and final. In the heats, each canoeist has two runs at the course with the better time counting. The top 15 advance to the semifinal. In the semifinal, the canoeists get a single run; the top 10 advance to the final. The best time in the single-run final wins gold.[7]
The canoe course is approximately 250 metres long, with up to 25 gates that the canoeist must pass in the correct direction. Penalty time is added for infractions such as passing on the wrong side or touching a gate. Runs typically last approximately 95 seconds.[7]
