There is also slolem and downriver whitewater kayak racing. In downriver you are timed in a race of speed only. In slolem, the racers have to negotiate a course of gates hanging just above the water. The gates are colored either&red or green and mean upstream or downstream. The racers have to go through these gates without getting penalties. 50 seconds for missing the gate, and 5 for hitting it. They are judged, and the winner has the best overall time.
