Description Available in: Canoe slalom, unlike its canoe sprint cousin, sees competitors complete timed runs down a white water course with up to 25 gates. Red gates must be negotiated upstream, while green gates must be negotiated downstream. Touching a gate adds a two-second time penalty to the run; missing a gate results in a 50-second penalty. The time taken to run the course in seconds is added to any penalties to give the overall score.
