Competitive racing (whether running, biking, skiing, or whatever) is usually carried out in one of two ways:
Two or more competitors start at the same time and race side-by-side; the first to cross the finish line is the winner.
Each competitor starts alone, with no other competitors in sight; each run is timed (or otherwise measured), and the person with the fastest time (or otherwise best score) when all competitors have completed their turn is the winner.
Category 1 normally includes disciplines like track, sprint, bike races, swimming, cross-country skiing, etc. Category 2 tends to include disciplines like downhill skiing and bobsled. Sports like javelin, ski jumping, high and long jump, etc., are done in the same manner, though time is not the standard measured there.
Do these two basic types of carrying out competitive racing have individual names? For example:
The slalom race was organised as a _____ event, while cross country was a _____ event.
