Rallying
Rally is a form of motorsport that takes place on public or private roads with modified production or specially built road-legal cars. It is distinguished by running not on a circuit, but instead in a point-to-point format in which participants and their co-drivers drive between set control points (special stages), leaving at regular intervals from one or more start points. Rallies may be won by pure speed within the stages or alternatively by driving to a predetermined ideal journey time within the stages.
Reliability trial
The term "reliability trial" is also used to refer to motorsport events and are similar in concept. Rather like rallying, drivers and their vehicles (or riders and their motorcycles) must complete a designated course within a set time limit, without recourse to outside help along the way.
