Course, logistics and awards

Courses run entirely on paved roads through old growth redwood forest and alongside a natural creek. The full marathon is a double out-and-back; the half marathon is an out-and-back. The route is described as mostly flat with gentle uphill sections. Tall redwood trees provide shade and can sometimes block GPS signals on watches. The course is USATF certified and the marathon is a Boston qualifying race.

Finishers receive a medal. Overall prizes are awarded to top finishers in the full and half marathons, including a non-binary category. Age-group awards are given in ten-year bands, with 19-and-under included in the half marathon. The 10K awards a first-place trophy. Award distribution occurs near the finish line. A spaghetti feed is planned with details to be announced. Visit the organization's website for the most recent information.
