100 Miler registration on UltraSignup is marked 'Closed Aug 20 @ 11:59 PM' while the 50K listing on the same page is marked 'Open' at the same time; the page's own text is internally inconsistent about which distances are still open 14 days before the race. Recorded as a conflict, not resolved.

The course

Where it goes point to point · 9 aid stations

The Dark Divide 100K: a point-to-point race from Wright Meadow to Cispus Learning Center, 60.74 measured miles with ~16,500 ft of gain and over 19,000 ft of descent, ~80% singletrack. Shares its entire route with the back half of the 100 Mile course from Wright Meadow through Juniper Ridge, then diverges onto its own return leg via Yellowjacket Creek and Burley Mountain Fire Lookout (the 100 Mile course returns to the finish via a shorter, more direct leg from its own second Juniper Ridge visit). No shuttle service exists between Cispus Learning Center and the Wright Meadow start; runners and crew are responsible for their own transportation.

Page prose states 'approximately 16,500 feet of elevation gain accompanied by over 19,000 feet of descent'; the official chart and course-sections document both give 16,587 ft gain / 19,031 ft loss, matching the course GPX exactly. CONFLICT, not resolved: the course-sections PDF's final row states the course finish at 'Cumulative Mileage 62.66 miles' in its per-section detail block, but the same document's own summary table row, the 2026 aid-station chart, and the official course GPX (<desc> '60.74 Miles') all independently agree on 60.74 miles. The 62.66 figure is treated as a stray error in that one PDF cell and 60.74 is used as distance_miles, but the conflict is recorded here rather than silently discarded. Separately, a nominal '100K' (100 km) is 62.14 miles; the measured course (60.74 mi / ~97.75 km) runs a bit short of that, which is normal for trail races and not itself a data conflict.

The race

What this one is

A wilderness trail-race weekend (100 Mile, 100K, 50K, 15 Mile) through the 70,000+ acre Dark Divide Roadless Area in the Gifford Pinchot National Forest, based at the Cispus Learning Center near Randle, Washington. The 100 Miler is a Hardrock 100 qualifier.

Wonderland Running founder Sean Harrasser has run the race since its start; a 2026 Facebook post from the organizer calls the 2026 edition "year six," placing the first edition in 2021. The race is dedicated in part to the memory of five-time Hardrock finisher Mike "Bushwhacker" Burke.

Crew rules
BEFORE REGISTERING: there is no shuttle service available in this remote area. Runners and their crew are responsible for transportation to/from Wright Meadow and Cispus Learning Center; Wonderland Running provides a rideshare spreadsheet to help coordinate, but there is no formal shuttle. wonderlandrunning.com
Pacer rules
Pacer pickup is marked on the official chart only at Juniper Ridge (mile 39.65) and Yellowjacket Creek (mile 47.48); no separate 100K-specific pacer-rules prose is published (see the 100 Miler course's pacer_rules, which is the general Wonderland Running pacer policy). wonderlandrunning.com
Drop bag rules
Drop bags allowed at stations marked Yes on the official aid-station chart; no size limit is published. Runners must carry a light source and spare batteries/charger from the race start (in the dark) until sunrise, and again after Summit Prairie AS (or available in their Summit Prairie AS drop bag). wonderlandrunning.com
Cutoff philosophy
This is not at all a beginner level ultramarathon; the course features technical trails, long steep climbs, and remote terrain with up to 11+ miles between aid stations. wonderlandrunning.com
