Kissena 400 Meter Track Markings

All tracks must have standard markings. Between the infield (sometimes referred to as an apron) and the actual track is the blue band (called "côte d'azur") that is typically 10% of the surface. The blue band is not a part of the track. Although it is not illegal to ride there, moving into it to shortcut another rider will result 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. This can easily result in a crash, and so this is why it is ill-advised to ride on the blue band.

20 cm above the blue band is the black line. The inner edge of this 5 cm line defines the length of the track. 90 cm 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 the optimum route around the track. A rider leading in this zone cannot be passed on the inside; other riders must pass on the longer outside route.

Minimum 250 cm (or half the track width) above the inside of the track is the blue stayers' 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) the released team rider rests, riding slowly above the blue line until his teammate comes around the track and pushes him back into the race.

The finish line is black on white and towards the end of the home straight. Red lines are marked in the middle of each straight as start and finish line for pursuit races. A white 200 m line markes 200 m before the finish.
