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.
