Tyler Armstrong
After reaching the top of Kilimanjaro, Armstrong started to look for a new challenge, which he found in Argentina. 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.
After months of preparation, Armstrong was ready for his journey to Argentina. On December 7, he left the United States. 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.
