They went up and down Makalu in 25 hours and 48 minutes. He intends to complete his entire Seven Summits that way.<\/p>\n<p>On Everest earlier this year, Egloff used the fixed ropes but not bottled oxygen. Nor did he ever stop his chronometer for rest breaks or to spend a few relaxed minutes on the summit.<\/p>\n<div id=\"attachment_105233\" style=\"width: 517px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-105233\" class=\"wp-image-105233 size-large\" src=\"https:\/\/explorersweb.com\/wp-content\/uploads\/2025\/05\/egloff-story-507x700.jpg\" alt=\"IG story with Karl Egloff\" width=\"507\" height=\"700\" srcset=\"https:\/\/explorersweb.com\/wp-content\/uploads\/2025\/05\/egloff-story-507x700.jpg 507w, https:\/\/explorersweb.com\/wp-content\/uploads\/2025\/05\/egloff-story-217x300.jpg 217w, https:\/\/explorersweb.com\/wp-content\/uploads\/2025\/05\/egloff-story.jpg 702w\" sizes=\"auto, (max-width: 507px) 100vw, 507px\" \/><p id=\"caption-attachment-105233\" class=\"wp-caption-text\">Egloff&#8217;s farewell before his attempt earlier this year.

Andrews even returned to <a href=\"https:\/\/explorersweb.com\/everest-surprise-tyler-andrews-returns-this-fall-for-speed-record-attempt\/\" target=\"_blank\" rel=\"noopener\">Everest in the fall<\/a>, taking advantage of the presence of skier Andrzej Bargiel&#8217;s large team, which fixed ropes and broke trail.<\/p>\n<p>Andrews was trying to beat the previous uphill mark of 20 hours and 24 minutes from Base Camp to summit, set in 1998 by Kazi Sherpa.
