In 2010, Tejas set the world record for the fastest period in which a person has climbed all seven of the world's highest mountain summits, at 134 days. He is also the only person to have summited all seven on at least ten separate occasions, and has climbed all seven twice within a year. He had previously held the record in 2005 at 187 days. During the period of the new record, he also scaled the Carstensz Pyramid in New Guinea.
