American ultrarunner Tyler Andrews summits Everest in nine hours, fifty-five minutes, an oxygen-assisted base-camp-to-summit speed record that erases Lhakpa Gelu Sherpa's 2003 mark by a full hour and one minute, with a 16:32 round trip on his sixth attempt in two years. We break down the physiology of roughly 11,500 feet of vertical over 8.4 miles through the Khumbu Icefall, the South Col, and the Hillary Step.\nThen we set the table for the HYROX World Championships in Stockholm, June 18–21 at the Strawberry Arena, where only the top half-percent of the sport even qualifies. We compare the three men we think decide it: Alexander Roncevic, who broke the sub-52 barrier at a blazing-fast Warsaw; defending champion Tim Wenisch; and the showman, three-time champ Hunter McIntyre — their fastest times, their three-race averages, and why Hunter going back to his strength roots (and chasing another wall-ball record) makes him our pick. Plus Swiss ultra-endurance rider Robin Gemperle wins a brutal, mud-clogged Unbound Gravel XL — 356 self-supported miles across the Flint Hills of Kansas in roughly 21 hours, on a prototype Scott 32-inch-wheel bike that will never hit the market, after walking close to a half marathon through the mud. And the world's first 24-hour treadmill ultra, where teams of four trade off across forty treadmills inside a factory-turned-rave, and why running in place might be the hardest endurance test there is.\nOn the science side, creatine is still mainstream. New work frames grip strength as a validated proxy for health span, biological age, and all-cause mortality risk, and ties consistent creatine intake to meaningful gains in lean body mass and combined grip strength, with favorable trends in bone mineral content and...","thumbnail_url":"https://img.transistorcdn.com/7tuPWtGzB4VZWD-SOt52XBn_D9_i6afR7P3Pmrw4i2Q/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS80ZmVi/OGExOWU4OGI0ZjI3/YWYzOTAyNGMyMTM5/Zjk5Zi5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
