Sunriver Half Marathon for a Cause

Sunday, September 6, 2020 • Sunriver, OR • Course Map

Note: The 2020 race has been cancelled.

Runners get the chance to trek through this 3,300-acre private resort community along the Deschutes River, near the base of the nearby Cascade Mountains, at the annual Sunriver Marathon for a Cause, which features a 5K and 10K on Saturday and a half marathon on Sunday.

Organized both to promote the cause of and raise funds for the Oregon and southwestern Washington state affiliate of Susan G. Komen for the Cure, the nationwide nonprofit that also organizes an annual three-day, 60-mile walk as its signature fundraising effort, the race proceeds will go to benefit the fight against breast cancer.

The race will follow an out-and-back course that starts and finishes at the Sunriver Resort, and then takes runners and walkers on a route with spectacular views of nearby Mount Bachelor, the more than 9,000-ft.-high stratovolcano that today is home to a ski resort.

The course, which is USATF-certified, next takes runners through the communities of Sunriver, Caldera Springs and Crosswater, all of which are known as “high desert” environments here in central Oregon.

The scheduled starting time for the Sunday race is 7:00 AM for the half marathon, and runners in the half marathon will have 3 1/2 hours to complete their race.

    Last yr you canceled sec. air quality. This yr is also questionable. How late can we sign up? [This is also to indicate that there are probably a lot of people waiting to sign for the same reason]

    Hi there, my best friend and i are looking to sign up for this race here soon and i am just curious if the date has a high chance of changing because we are also looking to book a house at sun river for that time.
