Oxbow Trail Runs

3010 SE Oxbow Pkwy

Gresham, OR Half Marathon, 10K, 5K

Registration closes: Thu, Sep 23 @ 11:59PM


The Oxbow Trail Run is a family fun event in the scenic Oxbow Regional Park, Metro, just outside Gresham on the Sandy River, about 30 minutes from downtown Portland.

UPDATE: Metro has approved the Oxbow Trail Runs for September 26th.  Registration will open the 6/10/2021 and is be capped at 100 total runners.  Rollovers from 2020 Trillium Blooms and Oxbow Trail Runs will be eligible to use credit for the 5k, 10k, and Half Marathon races.

Float or float? Spend the day at Oxbow

Originally we thought of floating a popular section of the Sandy River Water Trail 3.5 miles downriver to Dabney State Park after the run. However, no insurance company would allow it. So instead, each finisher gets a root beer float!

The Alder Picnic Area is reserved for participants and their guests for the whole day.   ETA will be serving complimentary sandwiches for participants to enjoy after the race.

There are two barbeques, so bring charcoal and food to throw on the grill. In addition, there are horseshoe pits and play structures, plus a trail down to the beach on the Sandy River.  Please note we may have to limit guests and spectators depending on Oregon's vaccination rate and the COVID-19 state restrictions.

Shuttle with a friend and float the river in a tube, boat, or kayak.  Follow the safety guidelines of the Sandy River Trail Guide.  Each river user's responsibility is to be safe as neither Northwest Dirt Churners nor Oregon Metro is part of the river float.

Reserve a camping spot and stay for the weekend. (COVID-19 protocols may restrict camping)


The 5k, 10k, and Half Marathon start and finish at the Alder Picnic Area in the center of the park next to the Sandy River. All races are cupless. The Half and 10k will have a water-only station for refills of handhelds, etc. at the four-mile (& 11-mile turnaround point.

5K– The 5k is fairly flat and a great way for new runners to get acclimated to running trails. The start of the run provides stunning views of the oxbow bend of the Sandy River and the foothills surrounding it. After a couple of miles, the course heads toward Elk Meadow and the Ancient Forest, a section of 700-year-old majestic trees in an old-growth forest.

10k- The 10k follows the 5k route for the first 2.3 miles, where the two distances split and the run climbs up to Alder Ridge. The trail circles around Elk Meadow. On a clear day, Mt. Hood appears between the towering Douglas Firs. On the other side of the plateau is an out and back along the equestrian trail. Runners will be treated with a 300' challenging climb in a half-mile to the road, only to turn around at the aid station and navigate the stairs and roots on the descent. Continue the loop on Alder Ridge past the moss of ferns of the forest to meet back on the 5k course and the Ancient Forest to the finish.
The Half Marathon will do the 10k loop twice with a short out and back in the Ancient Forest on the first lap.
