2023 ICF Canoe Slalom World Championships – Men's C1

The men's canoe event at the 2023 ICF Canoe Slalom World Championships took place on 22 September 2023 at the Lee Valley White Water Centre in London, with the qualification heats on 20 September 2023.

Competition format
The event uses a three-round format with qualification heats, semifinal and final. Paddlers complete up to two runs in the heats, with the top ranked athletes starting last. In the first heat, the 20 fastest paddlers qualify automatically for the semifinal, whilst the rest compete in the second heat for additional 10 qualification spots. The final rank of non-qualifying athletes is determined by their second run score. Paddlers start in the reverse order of their heats position in the semifinal and complete a single run, with the top 10 advancing to the final. The start list for the final is once again in reverse order of the semifinal results. The athlete with the best time in the single-run final is awarded gold.

A penalty of 2 seconds is awarded for touching a gate and a 50-second penalty is awarded for missing a gate or negotiating it in the opposite direction.

The heats setup had 23 gates including 6 upstream gates (3-11-12-15-19-23). The semifinal and final gate setup also had 23 gates with 6 upstream gates (3-11-12-15-19-23), but in a more difficult configuration, causing slower times.
