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.

Some were purpose-built just for cycling, and others were built as part of facilities for other sports; many were built around athletics tracks or other grounds and any banking was shallow. Reflecting the then-lack of international standards, sizes varied and not all were built as ovals: for example, Preston Park is 579 m (1,900 ft) long and features four straights linked by banked curves, while the 536 m (1,759 ft) 463: 304: 144: 427: 47: 351: 660: 593:, 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. 322:, allows riders to keep their bikes relatively perpendicular to the surface while riding at speed. When travelling through the turns at racing speed, which may exceed 85 km/h (52.8 mph), the banking attempts to match the natural lean of a bicycle moving through that curve. At the ideal speed, the net force of the 576:

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.

Between the infield (sometimes referred to as an apron) and the actual track is the blue band (called "cĂ´te d'azur") which is typically 10% of the surface.

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

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 (30 km or 19 miles, or more, compared to 3–10 km or 1.9–6.2 mi for most other races). The name is taken from

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

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

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

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 200 metres (660 ft) before the finish.

A rider leading in the sprinter's lane may not be passed on the inside; other riders must pass on the longer outside route. 624:. 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 495:

International Calendar may be held in velodromes that measure between 133 and 500 m (436 and 1,640 ft) inclusive, with a length such that a whole or half number of laps give a distance of 1 km (0.62 mi).
