The six major marathons are known as the World Marathon Majors and are some of the most prestigious and sought-after marathons in the world. These marathons are:
- Tokyo Marathon
- Boston Marathon
- London Marathon
- Berlin Marathon
- Chicago Marathon
- New York City Marathon
These marathons are organized annually and are recognized as the most high-profile marathons on the calendar. The Abbott World Marathon Majors is a championship-style competition for marathon runners that started in 2006 and is founded on these six major marathon races. The series comprises annual races for the cities of Tokyo, Boston, London, Berlin, Chicago, and New York, and each edition of the series recognizes and includes the results of the major global championship marathon held in that year. The Six Star Medal is awarded to runners who complete all six marathons, putting them into an exclusive club.
