There were 150 members of the North Pole Marathon Grand Slam Club on March 30th 2023, comprising 117 men and 33 women.

To be eligible for membership, you must have completed a recognized marathon or ultramarathon on each of the continents, exemplify the spirit of adventure marathon running and be able to authenticate your claim for membership. New members receive a Grand Slam medal.

Grand Slam contenders do not have to take part in specific marathons to become members, but you must be a member of the The 7 Continents Marathon Club ™.

Please note that a marathon on the Shetland Islands, including King George Island, does not count as 'Antarctica' as these islands are not within the Antarctic Circle, not on the Antarctic tectonic plate, and not on the Antarctic continental landmass or continental shelf.
