A Formula One race or Grand Prix is a sporting event which takes place over three days (usually Friday to Sunday), with a series of practice and qualifying sessions prior to a race on Sunday.Current regulations provide for two free practice sessions on Friday, a morning practice session and an afternoon qualifying session held on Saturday, and the race held on Sunday afternoon or evening, though the structure of the weekend has changed numerous times over the history of the sport.At most Formula One race weekends, other events such as races in other FIA series (such as the GP2 Series) are staged.
