Competitions are held at a number of events on the River Thames between April and October. Events are competed at four status levels from Novice to Senior, allowing the opportunity to compete for anyone from complete beginners and Olympic rowing champions. There are two types of skiff race, long-distance and regattas. In long-distance processional events, crews set off at time intervals over a course of two or more miles. At regattas, skiff races are non-processional sprint races held over a distance of up to 800 yards with heats and finals. Regatta races usually have one skiff against another, although three lane racing may also occur. There are a number of Trophy competitions. The Ormiston Trophy is awarded to the Club that wins the highest number of events each season overall, while the Inter-Club competition is a separate event for top scullers in each club.
