A race is a competition of speed, against an objective criterion, usually a clock. The competitors in a race try to complete a given task in the shortest amount of time. Typically this involves traversing some distance, but it can be any other task involving speed.

In North America, the cars used in the National Championship (currently the Indy Racing League IndyCar Series, and previously CART) have traditionally been similar though less sophisticated than F1 cars, with more restrictions on technology aimed controlling costs.
