Omnium is a term used in various contexts, but it is most commonly associated with the world of finance and insurance. In finance, it refers to a type of investment fund that pools resources from multiple investors to invest in a diversified portfolio. This allows individuals to access a broader range of assets than they might be able to on their own. In the context of cycling, "omnium" is a multi-race event in track cycling that includes several different races, such as sprints and endurance events. Cyclists compete in these races to accumulate points, with the overall winner being determined by their total score across all events. This format showcases a rider's versatility and skill across different cycling disciplines.
