In a year that will go down in Everest history, Ukrainian-American climber Andrew Ushakov became the fastest person to reach the top of the world's tallest mountain from sea-level, completing the mega-ascent in just three days, 23 hours and 7 minutes.
While all eyes were on a team of four British ex-special forces climbers who had drummed up publicity with their charity bid using Xenon gas, Ushakov quietly completed the ascent just after them, beating their time. What's more, he did it using only supplemental oxygen.
