Colin O'Brady

American professional endurance athlete and adventure Colin Timothy O'Brady just became the first person to cross Antarctica alone and unaided. He achieved this incredible feat on 26 December 2018.

          Born on 16 March 1985, O' Brady holds three world records:
          In 2016 he set the Explores Grand Slam ( Last Degree) and seven Summit speed record.
          He became the fastest person to complete the adventures challenges in 139 days and 131 days respectively.
          In the Summer of 2018, O'Brady set the speed record for the 50 US High points in 21 days.
          The 33- year-old skied 932 miles across the southern continent in 54 days without getting resupplied - which required him to carry everything he'd need throughout the journey on a sled . Everyone  who tried to accomplish feat before O'Brady either gave up or died.

          When he started his journey , his sled weighed 400 pounds- it contained a tent, sleeping bag, cameras, a satellite phone, and 30 pounds of fuel for cooking. Most of the sled's weight, however, came from 220 pounds of food - enough to help  O'Brady survive for more than two months.
          And what did he eat along the trip - oatmeal, freeze-dried meals, soup, and special "Colin Bars" that his sponsor, Standard process Supplements, made for him.

• O'Brady is a former professional triathlete. He represented the United States on the ITU Triathlon World Cup circuit, racing in 25 countries on six continents from 2009-2015.

• He is the world's first person to Snapchat from the summit of Mount Everest.
