Wonderland Running is immeasurably excited to announce some epic changes for the 2025 Dark Divide Trail Races! Read on!

So much new excitement for the 2025 Dark Divide Trail Races!!!

NEW RACE DATES!!!

The Dark Divide 100 Miler will take place starting Friday, September 5 with a 48-hour cutoff. New for 2025 is a 100k option on Saturday, September 6! Sunday, September 7 will see the Dark Divide 50k and 15 Mile Fun Run. There are no changes to the courses or cutoffs for the original Dark Divide distances. The Cispus Learning Center Pavilion will continue to be the start/finish area.

NEW DISTANCE OPTION!!!

The Dark Divide 100 Kilometer will make its inaugural appearance in 2025! This course offers many of the amazing highlights of the 100 Miler course, including alpine ridges, serrated peaks, lovely waterfalls, verdant meadows, towering old-growth temperate rainforests, and the best views of any Cascades trail race. But now in a long day without the 'overnight delight' of the 100 Mile race. Final course details & support decisions still need to be finalized with our permit, but what we do know it will highlight many of the existing course segments that feature outrageous alpine viewscapes, wild and technical ridge running, the most dedicated aid stations, and all the Dark Divide beauty we've come to know and love!

NEW ADDITIONAL AMENITIES!!!

This year we have use of the main campus at Cispus Learning Center! This is great news for us and you! We will have showers, kitchen, and a lot more parking. We also have bunkhouses available with a lot of beds. Beds at Cispus Learning Center may be reserved on Ultrasignup for $45 when you register. Of course, the usual camping options will also still be available.

NEW ONE-TIME, ONE-OF-A-KIND CASH PRIZES!!!

The Dark Divide 100 Miler's unique combination of steep terrain, very technical footing, and wild remoteness make this one of the most difficult (and beautiful!) courses you could ever run!
