29029 is an endurance events company whose flagship format asks participants to climb 29,029 vertical feet — the height of Mount Everest — on a single mountain within 36 hours, hiking up and riding the gondola down, lap after lap.
29029 Everesting Sun Valley runs September 10-13, 2026 on Bald Mountain at Sun Valley Resort in Sun Valley, Idaho (base elevation 5,750 ft). Each ascent gains 1,939 vertical feet over 1.6 miles of hard-packed dirt, rock, and gravel on the ski runs plus a fire-road section crossing Forest Service and BLM land. Fifteen ascents — about 24 miles of climbing — make the full 29,029 feet. Base camp is an on-mountain glamping village.
Entry is $5,595 for a single spot or $13,425 for a shared tent for two. It covers three nights in the glamping village, all food and beverage, a 20-week training plan, access to elite coaching and recovery services, limited-edition event gear, and a private online participant community. The nearest airport is Friedman Memorial (SUN).
This event is sold out. 29029 runs a waitlist from the event page linked above. Registration, waitlist placement, transfers, and refunds are handled directly by 29029, which sells and operates the event itself.
29029 is an endurance events company built around one idea: climb the height of Mount Everest — 29,029 vertical feet — on a single mountain. At its flagship Everesting events, participants hike one ski-resort ascent over and over for 36 hours, riding the gondola back down between laps, until they have banked the full 29,029 feet of vertical gain. Its second format, 29029 TRAIL, replaces the repeat-ascent structure with three mountain marathons on three consecutive days, roughly 79 miles total.
Both formats are all-inclusive hospitality events rather than conventional races: entry covers on-site or resort lodging, all food and beverage, a multi-month structured training plan, access to elite coaching, recovery services, and event gear. Fields are small and events routinely sell out well in advance, with waitlists managed by 29029. 29029 sells and operates every event directly through 29029.co.
