Loops through Zion National Park adjacent terrain. Red rock canyons, slickrock, sand washes, and desert scrub. Approximately 17,000 ft of gain.
April in southern Utah: 45–82°F. Spring conditions vary widely — can be warm enough for heat issues or cold enough for overnight layers. Low desert humidity.
Well-organized with crew access at multiple points. Spring wildflowers and canyon scenery make even bad patches beautiful.
The canyon terrain requires technical footing that prevents eating while moving on many sections. Athletes must eat proactively at aid stations and during the few flat runnable sections.
