The objective is to complete all three of Zion’s biggest canyons, Kolob Creek, Full Imlay, and Heaps in under 24 hours. Previously completed by Buzz Burrell, Jared Campbell, and Ryan McDermott in 2009 in 25 hours and three minutes. There is no order groups must do the canyon in, just that all three canyons must be completed in their Technical entirety.
The shortest possible distance is 28 miles, Or longer depending on the route chosen.
Kolob Creek Canyon 3C
starting from the west rim trailhead at Lava Point. Kolob Can be exited via the MIA exit, the standard route for most groups, or via boundary, sneak, a shorter option but more technical ascent.
7.8 miles Total, 2.5 miles Technical via MIA exit, 13 Repels up to 165 feet. Permit required
Imlay Canyon (full) 4B IV R
generally be accessed from the West rim trailhead at Lava Point, About 6 miles on The West rim Trail to Potato Hollow where full imlay begins. Imlay ends in the Narrows At floating rock, exit the Narrows to the temple of Sinawava. 11.4 miles Total, 3.2 miles Technical. 46 rappels up to 165 feet. Permit required.
From the temple of Sinawava Run just over 3 miles to the grotto trailhead and begin The climb up to Heaps Canyon
Heaps 4B IV R
heaps can be accessed from the bottom At the grotto trailhead or from the top at Lava Point, both are via the west rim Trail. There are multiple entrances to heaps, each with its advantages and disadvantages, most often people take the ridge entrance Near campsite four on the west rim Trail. Heaps is finished with a multi-stage big wall style repel sequence, culminating in a fully free hanging and exposed 300-foot rap Down to upper emerald pools. From here parties exit via Emerald Pools trails to the grotto, or the lodge.
10.5 miles Total from the grotto, 3.1 miles Technical, 18+ repels up to 296 feet.
I estimate the shortest distance possible for This subjective entirely uncut is around 28 miles, mileage increases as different routes are taken, or shuttles are used to access canyons from the top.
