5k, 10k, Half Marathon
The Oxbow Trail Runs a family fun event in the scenic Oxbow Regional Park, Metro, just outside Gresham on the Sandy River, about 30 minutes from downtown Portland. This year’s date for the Oxbow Trail Runs is September 10. Registration opens on June 1st. The 5k is a kid-friendly course, only $25 for those 18 and under.
Float or float? Spend the day at Oxbow
Initially, 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 day. ETA will be serving complimentary sandwiches (meat and vegan) for participants to enjoy after the race. In addition, there are horseshoe pits and play structures, plus a trail down to the beach on the Sandy River.
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.
The 5k, 10k, and Half Marathon start and finish are at the Alder Picnic Area in the park’s center next to the Sandy River. The 2023 course uses more trails next to the river, and the Half Marathon starts with a loop instead of an out and back. Each race is cupless. The Half and 10k will have water and Gnarly Nutrition aid station for refills of handhelds, etc., at the two-mile turnaround point and nine-mile point for the Half.
5K– The 5k is reasonably flat and a great way for new runners to get acclimated to running trails—the start of the run winds through the Ancient Forest before climbing on a gravel road. The 5k splits from the other courses and heads to the Sandy River, providing stunning views of the oxbow bend of the river and the foothills surrounding it. The boat ramp briefly breaks up the river trail, then continues down the river to the finish.
10k- The 10k follows the 5k route for the first mile, 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 on the river trails to the finish line.
Half Marathon will be two 10k loops with an extra mile circle on the river and through the Ancient Forest Trails on the first loop. The total elevation is 1560′.

Looks awesome! We’re registered for the 10k. I have a friend who walks but doesn’t run. Is the 5k walker friendly?
Thanks for registering Janell! The trails will be available all morning, so hikers are welcome. See you at Oxbow!
Is the Oxbow trail run a go? We had camping reservations for Friday and Saturday that just got cancelled by Oxbow park.
Thanks for asking. It looks like we have to cancel the race. We’ll send out an email soon.
Bummer, looking forward to 2021 and some sense of normalcy 😊
We will have Oxbow Trail Runs in 2021. Thanks for signing up and I hope to see you next year!
I am trying to see if I am signed up for the 5K at Oxbow park. My husband and I were registered for 2020. I thought we were rolled over for this year. His name is Martin Larsen.
I sent an email out a couple of weeks ago about rollovers. It might have hit your SPAM folder. I’ll send another out now.
What is the elevation gain for the half?
Thanks for the comment Moira. The half is basically two 10k loops with a fairly flat out and back in the Ancient Forest to make up the extra mile. So the elevation is just over 1700′ for the half marathon.
What is the time limit for the half?
@Angela- There isn’t a time limit for the half. We hope runners will be done in 4.5 hours, just so the sweeper isn’t out there all day. Based on your performance at Wine Country, you will be just fine.
