Skyrunning in the PNW! Come race the world's elite in the Olympic Mountains of Washington State.
The race start at (almost) sea level and follows a steep mountain trail - including a full VK on the upper section of the trail! - to the true summit of Mount Ellinor. Enjoy expansive views of the interior of the Olympics, including the glaciers of Mount Olympus to the north. To the south you can see Mount Rainier and Mount St. Helens in the distance. Once you past the second aid station you return on a different route to the finish.
The Forest Loop race is 5.5 miles and follows the Big Creek trail through lush PWN rainforest with an elevation gain of about 1,200ft. Enjoy several wooden bridge crossings over the stream at the high point of the course.

Updated course routes and maps with start/finish changes will uploaded soon!
Courses will be marked with bright pink and yellow ribbons. Yellow directional arrows are placed at all intersections and crossings.
Thanks to the efforts of the Mt. Rose Trail Crew, the track is in wonderful condition. Potential hazards include yellow jackets and horseflies the size of helicopters. Despite the danger, we ask that everybody remain on the trail (as long as it is safe to do so) to avoid any resource damage.
For Skyrace: We are asking you to be back at the finish in ~6hrs. If you would like to join us but are worried you won't make it in time we will allow you to start 30min early. Please reach out to us to arrange this. The spirit of our event is that you get to the summit and back as fast as you possibly can; this is an athletic endeavor and a test of fitness rather than a hike.
For Forest Loop: We are asking you to be back at the finish in ~2hrs.
Skyrace only: We will have a full stocked aid station mile 5.4 (at the upper trailhead parking lot). This aid station you will visit again on your return trip at mile 8.3. Our Aid station is stocked with water, Tailwind, soda, fruit, chips, pickles and a few other treats. Basic first aid supplies are available too.
There's no aid at the summit turnaround point!
We have post race food and aid available at the finish line for both races.
All our races are cupless events, thanks to our sponsor Hydrapak. Bring a collapsible cup for fluids at the aid stations. For folks who forgot their cup you'll be able to purchase one at race pickup.
In our effort to reduce waste we will have very few trash cans at the event. We aim to recycle an and compost most of our waste. Please be mindful of our environment.
Beast of Big Creek takes place in early August. Often the early part of the race the woods are shady and cool, but once you make it above tree line you will be exposed to the sun. Prepare for alpine conditions. Bring sunscreen and potentially an extra layer.
The trails are open to all other forest users on race day. Most everybody will be stoked to see you out there.
