The Club is unique, reserved for athletes who have run a marathon or ultra within the Antarctic Circle on the Antarctica continent, as well as on the other six continents. See The 7 Marathons Club Rules & Definitions. Membership is not conditional on paying a membership fee and it is the definitive and official list of people who have completed marathons on all 7 continents.

The Antarctic Ice Ultra™, the Antarctic Ice Marathon®, and the Antarctica Intercontinental Marathon® (part of the World Marathon Challenge®) are three official marathon events within the Antarctic Circle on mainland Antarctica.

New members of the Club will receive a club medal, OR, if completing 7 marathons on 7 continents in 7 days at the World Marathon Challenge®, will receive an Intercontinental Marathon Club medal.

In addition to the 7 continents, if you complete the North Pole Marathon®, you'll join the Marathon Grand Slam Club™ and will receive a Marathon Grand Slam Club medal.
