Best Dam Run – 10K & Half Marathon

Register/Volunteer | Results & Photos

The Best Dam Run course is lovely! Mostly on private closed road, it features views of the Clackamas River, cool forests, interesting geology and (if you’re lucky) bald eagles and osprey. The 10K is a speedy, net downhill point-to-point course, same as prior years. The half marathon course (first offered last year in 2023) is a Z-fold course — it starts out with the 10K, then at 3.45 miles, heads back towards the start, then turns around yet again to finish at the same finish line as the 10K, Broadway Street in downtown Estacada.

Special Notices for 2025

• ORRC is “eco-friendly.” We listened to prior concerns: In order to best support our participants, we provide paper cups at aid stations with water and Gatorade. And, we also encourage those who are willing to bring your own hydration, or reusable/refillable cup or bottle, to save on disposable cups. Read about our eco-friendly policy.

Swag

• All finishers will receive a pair of custom Fitsock Best Dam Run socks.
• Sorry, there will be no finishers medals for this event.

Registration

Day or race registration is offered, but signing up online earlier helps us plan better and saves you some money, too. When you register online as an ORRC member, you get $15 off the registration fees.

Volunteering

We need volunteers. You, a friend, or family can all sign up to volunteer! Event participants can volunteer before or after running or walking, too, as we need help for set up and take-down, too. As a thank you, every volunteer receives a discount off a future ORRC event. Learn more about volunteering with ORRC.
