A regularity rally, also called time-speed-distance or TSD rally, is a type of motorsport rally with the object of driving each segment of a course in a specified time at a specified average speed. The rally is usually conducted on public roads, but sometimes includes off-road and track sections. Contestants usually compete in teams composed of an amateur driver and navigator. Teams usually start a regularity rally at fixed intervals, creating a field that is spread along the course. [1]
Regularity rallying shares its origins with most types of rallying. Unlike the well-known 'special stage rallying' (which is commonly just called rallying), regularity rallying does not depend on the abilities of the driver at high-speed nor does it depend on the speed that the vehicle can achieve. For this reason, ordinary motor vehicles can be used. (Regularity rallies are commonly held for classic or even vintage cars, see below.) Regularity rallying, therefore, is a far less expensive sport and can be enjoyed by a far greater spectrum of people. With the commercialisation and increasing competitiveness of special stage rallying, many people have been financially excluded from the sport and have therefore created many cheaper alternatives. The closest motor sport to regularity rallying is road rallying. Unlike a road rally, a regularity rally focuses somewhat more on the maintenance of precise speeds and times rather than on navigation. Navigation does, however, still play an important role in regularity rallying.
A typical regularity rally may run for a few hours or it may run over a series of stages over a few days.
At the start, competitors are usually briefed about the event and may be required to submit their cars for inspection. Each team is given a route schedule prior to departure. This schedule contains information that the navigator will use to try to keep to the specified route and it contains information about the designated speeds and times for each segment of the route. On some rallies, more than one type of schedule may be prepared for different types of competitors.
Once a team is prepared, they will usually start the rally at a specific time unique to them. Along the route, the team will encounter marshals. The position of the marshals is usually not known to the teams. The time at which the team arrives at each marshal is recorded and used in the scoring. In some cases the marshals are hidden from view. Teams may also encounter open sections where they are guaranteed not to encounter marshals and are not subject to any time penalties. There may be various other features along the route including points at which teams must wait for an 'exact time of departure', points at which teams must record their own times, etc.
Every regularity rally should have a deterministic route schedule. This means that the organisers can work out the exact times that should be recorded for each team at all the relevant points along the route. The difference between a team's actual times and the correct times determine their penalties. (Lateness and earliness both attract penalties.) The team with the lowest number of penalties wins.
It is usually possible to compete in a regularity rally using only a car (or sometimes a motorcycle) and a stopwatch, but many regularity rallyists use various devices in an attempt to reduce their total penalties. The rules of each rally determine which devices are permitted. Some common aids include:
The roadbook or logbook is a type of map encoded with the correct road to be followed. It counts for all the information about the distances, time and average speed that must be followed throughout the race. It is through these sheets that the navigator will direct, as well as pace, the driver. At the rally the book is divided into several sections that may be of the following types:
Often, regularity rallies are held for owners of classic cars. Since regularity rallies do not involve high speed, classic cars are able to participate on an equal footing with other cars. Regularity rallying provides a practical and inexpensive sport for classic car enthusiasts.
Historic Rally Championship is featured in the FIA (Automobile International Federation) championship.
The Rallye Glenwood Springs is the longest continuously running classic car rally in North America. It has been held annually since 1952, starting in Denver, CO and running over 120 miles through the Colorado Rockies to Glenwood Springs, CO. [2]
The Cascade Classic Rally & Tour is a 4 day event held in Washington State and British Columbia in which participants travel over 400 miles over scenic back roads. The event has run annually since 1997 and is known for its fun and unique locations. [3]
A popular specific variety of classic rallying is the 1/100 Regularity Rally.
Motorcycle sport is a broad field that encompasses all sporting aspects of motorcycling. The disciplines are not all races or timed-speed events, as several disciplines test a competitor's various riding skills.
Rallying is a wide-ranging form of motorsport with various competitive motoring elements such as speed tests, navigation tests, or the ability to reach waypoints or a destination at a prescribed time or average speed. Rallies may be short in the form of trials at a single venue, or several thousand miles long in an extreme endurance rally.
The Monte Carlo Rally or Rallye Monte-Carlo is a rallying event organized each year by the Automobile Club de Monaco. From its inception in 1911 by Prince Albert I, the rally was intended to demonstrate improvements and innovations in automobiles, and promote Monaco as a tourist resort on the Mediterranean shore. Before the format changed in 1997, the event was a “concentration rally” in which competitors would set off from various starting points around Europe and drive to Monaco, where the rally would continue to a set of special stages. The rally now takes place along the French Riviera in Monaco and southeast France.
Wales Rally GB was the most recent iteration of the United Kingdom's premier international motor rally, which ran under various names since the first event held in 1932. It was consistently a round of the FIA World Rally Championship (WRC) calendar from the inaugural 1973 season until the rally's final running in 2019, and was also frequently included in the British Rally Championship.
Motorsport(s) or motor sport(s) are sporting events, competitions and related activities that primarily involve the use of automobiles, motorcycles, motorboats and powered aircraft. For each of these vehicle types, the more specific terms automobile sport, motorcycle sport, power boating and air sports may be used commonly, or officially by organisers and governing bodies.
The Safari Rally is an automobile rally held in Kenya. It was first held in 1953 as a celebration of the coronation of Queen Elizabeth II. The event was part of the World Rally Championship from 1973 until 2002, before returning in 2021. It is historically regarded as one of the toughest events in the World Rally Championship, and one of the most popular rallies in Africa. From 2003, a historical event has been held biennially.
A speedometer or speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards. Other vehicles may use devices analogous to the speedometer with different means of sensing speed, eg. boats use a pit log, while aircraft use an airspeed indicator.
The Mille Miglia was an open-road, motorsport endurance race established in 1927 by the young Counts Francesco Mazzotti and Aymo Maggi. It took place in Italy 24 times from 1927 to 1957.
The Carrera Panamericana was a border-to-border sedan rally racing event on open roads in Mexico similar to the Mille Miglia and Targa Florio in Italy. Running for five consecutive years from 1950 to 1954, it was widely held by contemporaries to be the most dangerous race of any type in the world. It has since been resurrected along some of the original course as a classic speed rally.
Targa timing is a system of timing used in car rallying. It was invented by John Brown, the Clerk of the Course for the Targa Rusticana, a road rally organised in Wales in the 1960s by Oxford University Motor Drivers Club. Targa timing became the standard timing method used on rallies for almost 20 years following its invention in 1963. However, it was eventually banned as it became widely abused—the standard method by which organisers could set very high average speeds in a manner that left no permanent record.
A cyclocomputer, cycle computer, cycling computer or cyclometer is a device mounted on a bicycle that calculates and displays trip information, similar to the instruments in the dashboard of a car. The computer with display, or head unit, usually is attached to the handlebar for easy viewing. Some GPS watches can also be used as display.
Motorsport marshals are mainly volunteer workers responsible for the safety of motor racing competitors. They are stationed at various points of danger around race tracks to assist them in case of any collisions, accidents or track problems. Marshals are also known as course workers, corner workers, corner crews, turn marshals, corner marshals, track safety workers, or rally marshals.
Classic rallying, or historic rallying, is a type of road rally suitable for most standard classic cars, with no special equipment needed. These rallies are more about enjoyment than speed, and can be a good introduction to historic motorsport. A classic road rally is not about speed; in fact, there are severe penalties for finishing too early. The idea of a rally is to travel from a point to another within a certain time, not too fast or too slow, trying to match a speed average set by the organizers.
The Silver State Classic Challenge is an authorized Open Road Racing event that is run since 1988 on a 90 mi (140 km) stretch of State Route 318 in Nevada, United States, which is closed for the occasion.
Open-road racing is a form of regularity rally carried out at high speeds on closed public highways, most commonly in sparsely populated parts of the Southwestern United States. Competitors attempt to set specified average speeds which can range from 80 to 150 mph or higher along courses ranging between 50 and 110 miles in length. At the lower speeds, unmodified production cars can be used, while straightforward safety modifications can permit powerful sports cars to reach speeds of 165 mph (266 km/h).
A special stage (SS) is a section of closed road at a stage rallying event used for timed speed tests. Racers attempt to complete the stage in the shortest time. A race on a special stage is coordinated such that each competing racer begins after a set interval, to reduce the chance of impedance by other competitors. Each special stage is usually between 10 kilometres (6.2 mi) and 30 kilometres (19 mi) in length. Some stages may be as long as 50 kilometres in length. A rally usually comprises approximately 15–30 special stages, over multiple days of an event. The driver with the lowest overall time for all special stages in an event is the winner.

The Chihuahua Express is a three-day stage rally or open-road race in Chihuahua, Mexico. The first edition took place in 2007 as a continuation of the Border Challenge rally (2005–2006). The Express comprises three daily stages: Chihuahua–Ciudad Madera, Chihuahua–Divisadero and Chihuahua–Ojinaga. There is also a qualifying stage on Thursday morning before the competition on Friday, Saturday, and Thursday. The starting order on Friday is determined by the order of finish in this stage.
The Silk Way Rally is an annual rally raid type of off-road race. The first Silk Way Rally was raced in 2009 from Kazan, Russia to Ashgabat, Turkmenistan. From 2010 to 2013, the race has taken place in Russia. The 2016 edition had a Moscow-Astana-Beijing route, the 2017 edition starts in Moscow and finishes in Xi'an, China.
The 1/100 regularity rally is a typically European format of regularity rally often for classic cars. As with other regularity rallies, the aim is not to be the fastest but rather to stay on the prescribed time across all timed checkpoints. Accordingly, 1/100 regularity rallies carry a negligible risk of damage to the vehicles and participants.
