The first person to reach the North pole, the South pole and the peak of Mount Everest - known as the Three Poles Challenge - was Erling Kagge (Norway), who completed the trio on 8 May 1994.
On 8 May 1990, Kagge reached the North Pole with Børge Ousland (Norway). On 7 January 1993, he reached the South Polo solo. On 8 May 1994, he summited Mount Everest, again solo.
