Hood Hundred Course Details

This 100 mile course offers a world-class scenic tour of Mt. Hood’s high country and its dryer, sunnier eastern backcountry, with fantastic crew access, well-appointed aid stations and exceptional volunteer support. The course format is a lollipop loop-style route—essentially a 20 mile outbound stem from Mt. Hood Meadows to a dynamic 60 mile figure eight loop, then the 20 mile ridgeline return to Mt. Hood Meadows for the finish. This is a true mountain ultra, with a suprisingly fast first half and a sneaky tough back half. Awe-inspiring views, trails and community support await along this challenging and incredibly diverse course!

Trail Etiquette

Many of the course’s trails are popular and used by multiple different groups. Please be courteous to other hikers, runners, and between Bennett Pass Aid Station #2 and #14, mountain bikers and sometimes equestrians. Obviously watch for vehicles on any road/doubletrack segments of the course. If you wish to pass another runner, ask for "passing on your left" or "passing on your right" before attempting to pass. Slower runners must yield the trail to runners wishing to pass. Hikers and runners have the right-of-way over mountain bikers, but fast-traveling bikers may not see you in time so always be vigilant.

Equestrians: Horses may be spooked by the sudden appearance of a runner, with potentially serious consequences to everyone nearby. Call out to the rider, stop and step off the trail to let oncoming horses pass. Runners should never pass a horse from behind without first notifying the rider and the rider instructs you when they are ready for you to pass.

Trail Work

At this time, we do not have a trail work requirement. However, we strongly believe ultrarunners should contribute some amount of volunteer trail stewardship each year, especially considering the significant use and dependence on public lands the sport of trail and ultrarunning requires.

We will work with our beneficiary, 44 Trails, to hold at least one trail work party in the months leading up to the race (likely May and/or June) and would love your participation-- dates and location TBA or posted on their website at https://www.44trails.org.
