The Sunriver Half Marathon for a Cause is a race with purpose. Pick your distance: Half Marathon, 10K, 5K or Kids Dash. Runners get the chance to trek through the 3,300-acre private resort community along the Deschutes River, near the base of the nearby Cascade Mountains, and all races wind through Sunriver’s most spectacular views. Benefiting St. Charles Cancer Center, proceeds from your race entry stays in the community and helps individuals who are going through cancer treatment. Your contribution enables St. Charles Cancer Center to offer patients financial assistance through groceries, gas cards, utility assistance and lodging; social workers who support patients through treatment; and integrative therapies including Reiki, acupuncture and massage therapy. These are just a few of the services developed to help cancer patients as they go through the active treatment of chemotherapy and radiotherapy.
