Short description: Race where athletes compete to be the fastest

"Time attack" redirects here. For the cryptographic attack, see Timing attack.

In many racing sports, an athlete (or occasionally a team of athletes) will compete in a time trial (TT) against the clock to secure the fastest time. The format of a time trial can vary, but usually follow a format where each athlete or team sets off at a predetermined interval to set the fastest time on a course.

Cycling

In cycling, for example, a time trial can be a single track cycling event, or an individual or team time trial on the road, and either or both of the latter may form components of multi-day stage races. In contrast to other types of races, athletes race alone since they are sent out in intervals (interval starts), as opposed to a mass start. Time trialist will often seek to maintain marginal aerodynamic gains as the races are often won or lost by a couple of seconds.

Skiing

In cross-country skiing and biathlon competitions, skiers are sent out in 30 to 60 second intervals.

Rowing

In rowing, time trial races, where the boats are sent out at 10 to 20 second intervals, are usually called "head races." Head races are typically held in the fall, winter and spring seasons. These events draw many athletes as well as observers. In this form of racing, rowers race against the clock where the crew or rower completing the course in the shortest time in their age, ability and boat-class category is deemed the winner.

Motorsport

In many forms of motorsport, a similar format is used in qualifying to determine the starting order for the main event, though multiple attempts to set the fastest time are often allowed. In rallying, the special stages are run in a time-trial format. Other forms of time trials in motorsport include hill-climbing and qualifying. A similar race against the clock or time attack is often part of racing video games. Time attack is a type of motorsport in which the racers compete for the best lap time. Each vehicle is timed through numerous circuits of the track. The racers make a preliminary circuit, then run the timed laps, and then finish with a cool-down lap. Time attack and time trial events differ by competition format and rules. Time attack has a limited number of laps, time trial has open sessions. Unlike other timed motorsport disciplines such as sprinting and hillclimbing, the car is required to start off under full rolling start conditions following a warm up lap in which they will have to accelerate out as fast as possible to determine how fast they enter their timed lap. Commonly, as the cars are modified road going cars, they are required to have tires authorized for road use.{{Citation needed|date=January 2023}

Europe hosts several Time Attack championships with Dutch Time Attack as one of the first, starting in June 2008. As to date this championship runs 4-6 races per year on CM.com Circuit Zandvoort, TT-circuit Assen, Nürburgring GP-Strecke (together with German Time Attack Masters) and occasional additional racetracks in Germany, Belgium or France. Dutch Time Attack is set up to host drivers from the very entry level up to full blown racecars with according drivers, divided over 5 classes.

Other events such as Gridlife offer a time attack event taking place in various locations across North America. The competition is divided into various groups based on car specification. The level varies from everyday driven vehicles to non road legal race cars. Each class also has its own set of rules and regulations on car specifications as the higher class one goes the less regulations one is faced with. The top 12 competitors regardless of class will participate in the Final grid event in which the driver is allowed one warm up lap, one hot lap, and one cool down lap. The hot lap, however, will not count towards the overall trackbattle event. There is also a seasonal championship with every class having a champion based on points earned throughout the season.

Video games

Many computer and video games include a time trial (also known as time attack) mode, in which the main goal is to complete levels—or, in some cases, the entire game—as quickly as possible. This mode prioritizes completion time ahead of other measures of success such as high scores. In cases in which a game does not have a dedicated time attack or trial mode, a fast completion is frequently known as a speedrun.

The inclusion of a time attack mode can often be an effective way of adding replay value to a game. Racing games may also include ghost cars recorded by the development staff—attempting to beat their times can provide a final challenge to players who have mastered the rest of the game. Often the game provides other incentives to use the time attack feature; GoldenEye 007 and Tomb Raider Anniversary encouraged players to revisit levels more than once by offering unlockable cheat options as a reward for completing them within target times.

Both speedrunning and time attacking have extensive online communities dedicated to achieving the fastest times possible, with one popular website being Speedrun.com . . Amongst the community there are many speedrunning competitions, some held annually or otherwise inaugurally, such as Games Done Quick (GDQ).
