Polar regions of Earth
The southern polar region has no permanent human habitation. McMurdo Station is the largest research station in Antarctica, run by the United States. Other notable stations include Palmer Station and Amundsen–Scott South Pole Station (United States), Esperanza Base and Marambio Base (Argentina), Scott Base (New Zealand), and Vostok Station (Russia).
Antarctica Marathon
The Antarctica Marathon may have been the first for-profit sporting event held in Antarctica, on January 28, 1995. The event is now held every year in late February or early March. The race is held on King George Island, one of the largest Antarctic Islands just off the Antarctic Peninsula. There is also a half-marathon held at the same time. The start and finish is at Bellingshausen Station (the Russian base), and the course passes the Artigas Base (Uruguayan), the Frei Base (Chilean) and the Great Wall Base (Chinese). The course follows a gravel road that connects the bases.
