K2 summit in a career-Youngest in the world
Shehroze Kashif became the youngest ever to summit K2. He also holds the same record on Broad Peak which earned him the title of Broad Boy. Shehroze holds the record of youngest Pakistani to summit Mt. Everest.

2nd K2 summit in a career-Youngest in the world
Sajid Sadpara scaled K2 for the second time in his mountaineering career. His first summit was in 2018 at the age of 20. Now, he holds the record of youngest in the world to summit K2 twice.
2nd summit in career
Ali Durani from Pakistan became the 2nd youngest in the world.
3rd K2 summit in career
Garret Madison from the U.S equaled the record of the K2 summit thrice in their career. Fazal Ali’s 4th times K2 summit news was not true and dusted by Fazal’s family.
Sajid Sadpara’s accomplished mission
Elia Saikaly, Sajid Sadpara, and PK Sherpa remained two nights at C4 without supplemental oxygen. Sajid worked two days above 8000m to secure bodies, went for the summit, and brought back his father’s body 400m down. The iron man Sajid was the man who made the 2021 expedition so distinctive and set an example of resilience against the hardships of life. His efforts to secure the body of his father were matchless, equal to none.
