Mountaineering careerEdit


Armstrong started his career as mountain climber at the age of 6 after watching a documentary about hiking.[2] After finding out that the youngest person that ever climbed Mount Whitney was 9 years, Armstrong started to train every day and soon started to climb his first mountains.

Armstrong has hiked in ice, snow, rain, and heat. He has dealt with altitude sickness and hiking in the dark. Armstrong carries most of his own gear including poles, water, food, and clothing. His workout consists of running 4.5 miles on hills and walking an hour a day on a treadmill.[3] He also hikes every month with his father.[4]


Mount Whitney (July 26, 2011) – 14,495 feetEdit

After months of training, Armstrong climbed Mount Whitney in a single day on July 26, 2011.[5] At 7 years old, he might be the youngest boy to climb the mountain, with a 6-year old girl, Eva Luna Harper-Zahn, summiting in 2018. [6][7] Starting at the base camp, his 11-mile hike to the top, with an elevation gain of more than 6000 feet, took him 7 hours and 50 minutes.[2]

Mount Kilimanjaro (July 1, 2012) – 19,341 feetEdit

Although Mount Kilimanjaro had a minimum age limit of 10 years old, Tyler obtained a special permit to climb to the top.[8] He took the Lemosho Route, which took him eight days of climbing round trip. In those eight days, he hiked 48.5 miles and gained 10,644 feet of elevation. On July 1, 2012, Tyler was the second youngest person to reach the top at the age of 8.

Mount Aconcagua (December 24, 2013) – 22,837 feetEdit

After reaching the top of Kilimanjaro, Armstrong started to look for a new challenge, which he found in Argentina.[9] Mount Aconcagua was his new target, and being the youngest person to climb it was his goal. As a training exercise, he climbed Mount Baldy on August 17, 2013, as part of the fifth annual Climb to Cure Duchenne.[10] After months of preparation, Armstrong was ready for his journey to Argentina. On December 7, he left the United States.[11] He spent his first couple of days trying to get a special permit because the minimum age for climbing Mount Aconcagua is 14. After obtaining a special permit, Armstrong started his climb on December 15, taking the Polish Glacier Traverse Route. On December 24, 2013, Armstrong reached the top and broke the record for being the youngest person to climb Mount Aconcagua, at the age of 9, making headlines all over the world.[12][13][14][15]

Denali (June 2016) — 20,310 ft (6190 m)Edit

At the age of 12, Tyler was denied a permit to climb Everest in the spring of 2016. Instead, he planned to climb Denali.[16] In June 2016, he went to Denali and reached the summit with his dad.[17] The youngest to summit Denali (then known as Mount McKinley) was 11-year-old Galen Johnston in 2001.[18] During 2016, about 1000 people tried to summit Denali during its climbing season,[18] incl ud Romanian girl who reached the summit in May 2016 while working on her Seven Summits quest.[18] Denali was previously climbed and summited by a 12-year-old girl in 1995.[18] Even though they're young, the climbers had mountaineering backgrounds, and it's common for young teens to be on U.S. mountains, especially for skiing.[18] One ski instructor who works with young teens did not think it was unreasonable in terms of safety for people of this age to be on Denali, despite its size.[18]

Mountains climbedEdit

Armstrong has climbed the following mountains:[19]


Tyler has set the following records:

  • July 26, 2011 – Youngest person to climb Mount Whitney in a single day, at the age of 7.

Duchenne muscular dystrophy awarenessEdit

When Armstrong was climbing Mount Whitney with his parents, he met a boy crippled by Duchenne muscular dystrophy.[20] Armstrong made it his goal to help find a cure for the disease and partnered with the CureDuchenne Foundation.[23] By climbing mountains, he hopes to raise money and awareness for this disease.[5] By the summer of 2016 he had raised 25,000 for this disease out of a goal of one million dollars (USD).[20] Several hundred thousand people, mostly boys are afflicted by DMD, which is a fatal genetic disorder that typically cripples the afflicted by their teens and it is rare for them to make it to 30.[20]

In addition to climbing he also hosted a special fund-raising movie presentation of Everest, with proceeds going to CureDuchenne foundation.[20]


Armstrong is featured in a book called Stand Up! This anthology features stories by 75 of the world’s most dynamic young activists who share their amazing experiences. Armstrong's story is called “Kilimanjaro for a Cause!” and it is in the Adventures Seekers chapter of the book.
