A mass-start track event comprising teams of two riders per team. It is similar to a team points race, as points are awarded to the top finishers at the intermediate sprints and for the finishing sprint. Only one of the two team riders is racing on the track at any one time, riding for a number of laps, and then exchanging with their partner by a hand sling. The name comes from the original Madison Square Garden, which was constructed as a velodrome.
