Explorers Grand Slam
The original concept involved the polar trips starting from accepted coastal points, involving long sledging journeys. Over time the significantly shorter, easier and less serious "Last Degree" polar trips – from 89 degrees to the pole (at 90 degrees) – have been claimed as the Explorers Grand Slam (Last Degree). Currently, the climbing community and other leading organizations including the American Alpine Club, The Explorers Club, climbing companies such as International Mountain Guides, and the popular press all define the Explorers Grand Slam as having accomplished the Seven Summits plus (at a minimum - the last degree of) the North and South Poles. There is some consensus that a True Explorers Grand Slam means one will also have summitted all 14 peaks above 8,000 meters (14 + 7 + 2). Likewise, there is some consensus that a True Adventurers Grand Slam is achieved by also visiting the magnetic north and south poles.
David Hempleman-Adams became the first person to complete a Explorers Grand Slam in 1998. In April 2005, Park Young Seok became the first person to complete a True Explorers Grand Slam. In June 2018, Zhang Liang became the second person to complete this kind of Grand Slam. In 2011, former Wales rugby union international Richard Parks became the first person ever to complete the (Last Degrees) Grand Slam within a single calendar year, doing so within seven months. Cheryl Bart is the first Australian female and the 31st person worldwide to complete the Explorer's Grand Slam. She completed the North Pole on 22 April 2013 AEST. Vanessa O'Brien became the first woman to complete the (Last Degree) Grand Slam under a single calendar year, doing so in eleven months.
In 2014 Ryan Waters became the first American to complete "True Adventurers Grand Slam" by skiing full-length, unsupported and unassisted North and South Pole expeditions and climbing the seven summits. o
On 21 April 2015 Tashi Malik and Nungshi Malik became world's first twins and siblings as well as the first South Asians to complete the Explorers Grand Slam (last degree).
Colin O'Brady is the current world speed record holder for completing the Explorers Grand Slam (Last Degree). He became the fastest person to complete the challenge, doing so in 139 days on 27 May 2016.
Marin Minamiya became the youngest person to complete the Explorers Grand Slam (last degree) at 20 years old on April 12, 2017.
