in which they balance the bicycle on the sloped surface while keeping their feet locked into the pedals. For these reasons, the banking tends to be 10 to 15 degrees less than physics predicts. Also, the straights are banked 10 to 15 degrees more than physics would predict. These compromises make the track ridable at a range of speeds.
From the straight, the curve of the track increases gradually into the circular turn. This section of decreasing radius is called the easement spiral or transition. It allows bicycles to follow the track around the corner at a constant radial position. Thus riders can concentrate on tactics rather than steering.

Velodrome tracks can be surfaced with different materials, including timber, synthetics and concrete. Shorter, newer, and Olympic quality tracks tend to be timber or synthetics; longer, older, or inexpensive tracks are concrete, macadam, or even cinder.
Track markings
![Velodrome track markings](https://upload.wikimedia.org/wikipedia/commons/7/7e/Velodrome_track_markings.jpg)
Important cycling events are usually held on tracks which have lines laid out in a specified arrangement. Some other tracks also follow these protocols, but others have a different arrangement of lines to suit their facility and to assist riders in holding a straight line and in avoiding drifting onto the flatter section below the bankings where they risk their tyres sliding out.
Between the infield (sometimes referred to as an apron) and the actual track is the blue band (called "côte d'azur") which is typically 10% of the surface. The blue band is not technically a part of the track; although it is not illegal to ride there, moving into it to shortcut another rider results in disqualification. During time trials, pursuits or other timed events, the blue band is obstructed with sponges or other objects. The blue band is a warning to cyclists that they may scrape their pedal along the infield when in a curve, which can easily result in a crash.
above the blue band is the black measurement line. The inner edge of this line defines the length of the track. above the inside of the track is the outside of the 5 cm wide red
sprinter's line. The zone between black and red lines is sprinter's lane, which is the optimum route around the track. A rider leading in the sprinter's lane may not be passed on the inside; other riders must pass on the longer outside route.
Minimum (or half the track width) above the inside of the track is the blue stayer's line. This line serves in races behind motorbikes as a separation line. Stayers below the blue line may not be overtaken on the inside. In
Madison races (named after six-day races at Madison Square Garden in New York City, New York and also known as "the American"), the team's relief rider rests above the stayer's line by riding slowly until his or her teammate comes around the track and throws him or her back into the race.
The finish line is black on a wide white band and near the end of the home straight. Red lines are marked in the exact centre of each straight as start and finish line for pursuit races. A white 200 m line marks before the finish.
Track construction
Velodromes may be indoors or outdoors. In the heyday of velodrome racing (1890–1920), indoor tracks were common. When hosting six-day races, they were popular for revellers and urban sophisticates to congregate in the early hours after the bars had closed. Indoor tracks are not affected by weather and are more comfortable for spectators. They ride smoother and last longer. Despite the advantages of indoor tracks, outdoor velodromes are more common, as an outdoor venue does not require a building, making it more affordable, especially when new. Today, although many classic indoor tracks have been torn out of buildings and replaced by venues for more popular sports, velodromes are still sometimes built into indoor venues, particularly where track racing can generate enough revenue to cover the expense of dedicating a building to it.
Race formats
There are a variety of formats in velodrome races. A typical event will consist of several races of varying distances and structures. Common types of races include:
*
Scratch race

assigns value to specific laps throughout a race, e.g. every tenth lap. Generally the leading rider and sometimes the second place rider will be awarded points. The structure and timing of points races varies greatly, but the winner is determined by the accumulation of points and not necessarily the rider crossing the line first at the end of the race. Standard points races can have sprints every ten laps with the first three or four riders scoring, while

, also known as the ''Devil'', from the phrase "devil take the hindmost", or "miss and out", removes the last place rider from each lap (every second lap on shorter tracks) until only a few riders, often the final two, remain. The final standings are then determined by a rolling start match sprint over the last two laps.
*
Madison races team up pairs of riders in a tag-team format. Riders "sling" their teammate forward to facilitate alternating sprints that keep the pace very high during typically long races (, or more, compared to for most other races). The name is taken from
Madison Square Garden where the format was popular in the early 1900s. Since partners can trade as often as they like, this is a very busy race format, with half of the racers racing and half circulating around the track at any time. Historically the race was decided by which team had 'taken' the most laps, i.e. lapped the field, with points or finishing position only used to separate ties. In modern Madison racing, however, points scored in sprints decide the race, with a gained lap gaining a large points bonus. As a result, the Madison race is now essentially a team points race.
*
Time trials include team pursuit, team sprint, individual pursuit, kilo and 500 metre time trials, and the 200m flying lap. Cyclists or teams compete alone or in pairs against the clock alone, with times deciding the winner. In team events, drafting plays an important part in the discipline. while in pursuit events, an alternative means of victory is to 'catch' your opponent by making up the distance between the two start positions on opposite sides of the track. The flying lap was formally part of the Omnium event, but is now reserved for the qualification stage of match sprint events to determine seeding.
*
The Hour is a notable and unique event where a rider attempts to cover the furthest possible distance in one hour, as opposed to a set distance in the fastest time. This is not held as a championship event but as an occasional challenge event for an elite time trialist.
*
Sprints, also known as 'match sprints', are short, highly tactical races involving two or three powerful track cyclists over a short course of three laps from a standing start, each trying to take advantage of drafting their opponent, or alternatively getting a gap to prevent their opponent drafting behind them, before breaking into an extremely fast final sprint for the line.

. The Derny gradually accelerates until the last lap and a half when it pulls off the track, leading to a sprint for the finish to determine the winner.
*
Omnium
An omnium (from Latin '' Omni'': of all, belonging to all) is a multiple race event in track cycling. Historically the omnium has had a variety of formats. In recent years, road racing has also adopted the term to describe multi-day races that fe ...
competition assigns a point value to final standings of each race and riders accumulate points over the course of an event or series of events. This is not a specific race, but a competition that ties races and events together, and comparable to a heptathlon, decathlon in athletics, or modern pentathlon. Four endurance events comprise the current Olympic and World Championship Omnium: Scratch, Tempo, Elimination and Points race and must be completed within a day.
Team Sprint, sprint, Keirin, Kilo and flying laps are generally considered 'sprinters' races, which in track cycling equate to extremely powerful, muscular riders over short distances, resulting in some historic overlap between BMX riders and track sprinters, such as
Chris Hoy. The other events are considered endurance events for riders with less outright power but greater aerobic ability, and such events have historically enjoyed an overlap with elite road racers, including road sprinters such as
