About Wine Country Trail Runs

July 28, 2024

5k, 10k, & Half Marathon

The Wine Country Trail Runs occur at Chehalem Ridge Nature Park near Gaston, OR.  Oregon Metro bought this former 1260-acre Douglas Fir tree farm and restored the area to its natural beauty.  The ten miles of well-groomed gravel and dirt trails allow visitors to wander through evergreens, maples, white oaks, madrones, ferns, and streams flowing to the Tualatin River.  Views of the Cascades, Coastal Range, and the Tualatin Valley are obtainable at different vistas in the park.  Oregon Live called Chehalem Ridge an instant classic in the Willamette Valley.


Finishers over 21 can enjoy a splash of wine from Ardiri Winery and Vineyards.


The park is located near the heart of Willamette Valley’s wine country. No matter which direction you are coming from, Beaverton, Forest Grove, or Newberg, you’ll see rolling vineyards along the way.  Click this link for wineries in the area.

Adaptive Races

Northwest Dirt Churners is proud to have adaptive trail races of 5k and 10k distances. Adaptive racers will start at 8:45 am. The trails at Chehalem Ridge for the 5k and 10k routes are safe and accessible for adaptive racers. Some of the switchbacks have tighter turning radii which may be difficult for some users, depending on their equipment. Participants may have to go slow on some of the turns on the Woodland Trail.

Land Acknowledgement

Northwest Dirt Churners recognizes that the trails in Chehalem Ridge Nature Park run through the traditional lands of the Chehalem and the Atfalati people (also known as the Tualatin Kalapuya).  We thank these indigenous tribes and their descendants for being these spaces’ original and continuing stewards.

What to expect

The Wine Country Trail Runs is open to all levels and types of runners.  The 5k is relatively flat and on the dirt Timber Road and pea gravel.  There is no cut-off, so run, hike, or both.  The 10k and half marathon runs are a little more challenging but not too difficult.  All runs will start at different intervals, but runners will be on the course simultaneously.

Runners are rewarded with stemless wine glasses at the finish. In addition, ETA will serve food with vegan options to enjoy in the picnic areas. Participants over 21 can enjoy a splash of wine from Ardiri Winery and Vineyards. Tastings will also be available from Aridiri.


Chehalem Ridge Picnic Area


All races start and finish at the junction of Timber Road and Woodland Trail by the park’s entrance.  Each race begins running down Timber Road and ends on Woodland Trail.  The half marathon will have two aid stations, the 10k will have one aid station, and the 5k will not have any aid stations or water stops.  The park will be open to all users during the event, including mountain bikes and horses.

There will be water and Honey Stinger electrolyte drinks at the start, so bring a hydration vest, water bottle, or handheld for the run.

Chehalem Ridge Nature Park Trails and backgrounds (from Bobcat at Oregon Hikers)

Chehalem: ‘outside place’ in Atfalati (Northern Kalapuya); also the name given to a local band of the Atfalati
Ayeekwa Trail: ayeekwa is Atfalati for ‘bobcat’
Ammefu Trail: ammefu means ‘mountain’ in Atfalati
Mampał Trail: mampał = ‘lake’ in Atfalati; probably referring to Wapato Lake, which once existed near Gaston, was converted to onion fields, and part of which now is being restored as a national wildlife refuge.
Zorzal Trail: zorzal = Spanish for ‘thrush’
Castor Trail: castor is Spanish for ‘beaver’
Madrona Trail: the madrone tree (Arbutus menziesii)
Witches Butter Trail: Witch’s butter (Tremella mesenterica) is an orange-colored jelly-like fungus that is parasitic on fungi that inhabit decayed logs.



5K- The 5k starts down Timber Road for 3/4 of a mile and turns right on Ayeekwa Trail.  Ayeekwa Trail follows a creek and past a beaver dam.  Halfway through the run, turn left on Witches Butter Trail toward Timber Road.  Take a left on Timber for a short jaunt and then right on Woodland Trail.  Follow Woodland Trail to the finish.
