SIUSLAW DUNES 25K

25K across the Oregon Coast’s most untamed terrain!

March 7, 2020



25K

The Siuslaw Dunes 25K course offers magnificent views on a lollipop-loop style course along open dunes, remote ocean beaches and some forested single track trails. The course is dog friendly, so bring your capable adventure pup with you. The course is a touch long, at 16.6 miles (27K) to be exact, so, bonus!

This is an incredibly diverse course and there is nothing else like it anywhere. Runners travel through an assortment of ecological zones, including lush old growth coastal rainforest, riverside estuaries, freshwater lakes, as well as a fascinating transition zone between the dunes and the ocean called the deflation plain, which teems with water-loving plants and animals.

ELEVATION CHANGE

The course includes approximately 1,300' of ascent along with 1,300' of descent. 

COURSE SURFACES

The race’s surfaces intermittently change and alternate continuously throughout the race, presenting a unique challenge that will demand a runner’s attention and fitness. For example, over a 5 mile stretch, a runner would see a mile of beach, then a 0.5 mile sandy trail, cross a patch of open dunes, then enter 2 miles of forested singletrack trail, and so on. Overall, the 25K consists of the following surface types and approximate mileage TOTALS by surface type (not the order in which they are run):

  • 3.0 miles of forested dirt single track (classic dirt trail with some roots)

  • 1.5 miles of ocean beach (firm wet sand)

  • 3.7 miles of shore pine forest/sandy trail (somewhat firm and easily runnable)

  • 8.0 miles of open dunes split into two 4 miles portions (firm like wet beach during winter and early spring with some looser sections on hills and drifts)

  • 0.4 miles of paved path

AID STATIONS

There are two aid stations (one station passed two times) staffed with enthusiastic volunteers offering tasty fuel: Tailwind energy drink, water, soda, gels, Skout bars, bananas, oranges, chips, PB&J sandwiches, and more. All Daybreak races are cupless, so be sure to bring your own cup for liquid at aid stations.

Course Detail By Section: 

Start to Aid Station 1 (Waxmyrtle Trailhead): Runners depart the Cleawox Day-Use Lodge on a lakeshore path for half a mile around Cleawox Lake, past the Sand Dunes Day-Use parking area before entering the Oregon Dunes National Recreation Area. Runners follow a southerly route following course markings across the open dunes and are immediately greeted with sweeping views of the Oregon Dunes for 4 miles. The course follows a series of Forest Service sign posts, indicating the boundary between non-motorized use and motorized use. Please keep these sign posts on your right, so you remain in the non-motorized area. Exiting the open dunes, the course enters onto a forested sandy trail for .75 mile to Incinerator Trailhead at a flat paved forest road that parallels Siltcoos River. The forest road is followed west for .25 mile to Waxmyrtle Aid Station at Waxmyrtle Trailhead. From the start, it’s 5.5 miles on rolling terrain to Waxmyrtle Aid Station. 

Aid Station 1 (Waxmyrtle Trailhead) to Aid Station 2 (Waxmyrtle Trailhead 2): Leaving Waxmyrtle Aid Station, runners enter a rolling riverside estuary trail for 1 mile that ends at the beach. Runners head south along this .75 mile section of remote ocean beach, which feels almost like a wilderness full of great blue herons, sandpipers and gulls, with very few signs of human presence. The course exits the beach at the Carter Dunes Trail, a relatively flat meandering path through some lovely shore pine, salal and waxmyrtle forest for approximately .5 mile to the junction with Taylor Dunes Trail. Veer right at the trail junction to begin the counterclockwise loop portion. Half a mile after the junction, the trail arrives at Carter Lake Campground road. Turn left on the road way for a quarter mile, then turn left onto Taylor Dunes Trail. Taylor Dunes Trail meanders through a mix of forest and sand trail for 1 mile to complete the loop and return back to the beach on Carter Dunes Trail. Runners follow the beach back north for .75 mile to Waxmyrtle Trail, then follow it back to Waxmyrtle Aid Station.

Aid Station 2 (Waxmyrtle Trailhead 2) to Finish (Honeyman State Park): Runners leave the Waxmyrtle Aid Station along the paved forest road over to re-enter the hilly forested sandy trail at Incinerator Trailhead. Upon re-entering the main 4 mile open dunes section of the course, remember to keep the Forest Service sign posts on your left in order to remain in the non-motorized area of the dunes. After 4 miles on the dunes, you’ll see Cleawox Lake, and know you’re almost back to the finish! The course then descends down the last dune to the lake shore path (yes, you will hear and see us cheering for you!) for the final half-mile around the lake where runners finish at the Cleawox Lake Day-Use lodge patio with hugs and high fives with friends and family!
