Beneficiaries A portion of each entry fee will be donated to Douglas County Open Space. With nearly 800 acres in parks and more than 200 miles of trails, Douglas County Park Rangers work hard so that we can enjoy this wonderful beauty. If your organization would like to take part in the event, let us know. We need groups to volunteer at aid stations and race registration. Each group that has volunteers sign up will receive a donation. Contact Jessica via email for details.
