Prepare for a captivating trail running experience at the Oxbow Trail Runs, set for April 26, 2026, in scenic Oxbow Regional Park, Gresham, OR. This family-friendly event, presented by Northwest Dirt Churners, offers a Half Marathon, 10K, and 5K, appealing to both seasoned trail veterans and those new to dirt paths. Starting and finishing at the Alder Picnic Area along the Sandy River, runners will navigate a diverse landscape of well-groomed singletrack, old-growth forests, and picturesque riverfront trails. Typical race day conditions in late April offer pleasant highs around 65F and lows near 45F, with only a 15% chance of precipitation, providing ideal weather for tackling the varied terrain.

The courses are designed to showcase the park's natural beauty and offer a fitting challenge for each distance. The 5K is relatively flat, winding through the Ancient Forest before following the Sandy River, offering stunning views of the oxbow bend. For those seeking more elevation, the 10K climbs Alder Ridge, circling Elk Meadow with potential glimpses of Mount Hood on a clear day, and includes a challenging 300-foot climb over half a mile before descending back to the river trails. Half Marathon participants will complete two loops of the 10K course, augmented with an additional mile through the Ancient Forest trails on the first loop, accumulating approximately 1560 feet of elevation gain across the half marathon distance. Aid stations for the 10K and Half Marathon provide water and Honey Stinger electrolytes, though all races are cupless, so runners should bring their own reusable hydration systems.

The Oxbow Trail Runs is celebrated for its relaxed, grassroots atmosphere and community focus. Finishers are rewarded with unique Oxbow cups and delicious root beer floats, along with complimentary post-race sandwiches (meat and vegan options) provided by ETA catering. The Alder Picnic Area is reserved for participants and their guests for the entire day, encouraging a festive post-race gathering with horseshoe pits, play structures, and easy access to the Sandy River beach. Runners praise the event for its blend of challenge and accessibility, nature immersion, and small-race charm, making it an excellent choice for an early-season adventure or a memorable family weekend, with camping opportunities available in the park.
