Redding Marathon Events : course and race format

The Redding Marathon Events include a full marathon of 26.2 miles, a three-person marathon relay, and a certified 5K that finishes at the Sundial Bridge. The marathon start is at Shasta Dam in Shasta Lake City and the course follows paved trails that parallel the Sacramento River for much of the route.

The route description notes an initial descent after crossing the dam, a first relay transition around 9.7 miles, a section through Old Shasta between about miles 10 and 18, and a return to the river trail for the final miles. The course crosses the historic Diestlhorst Bridge near the second relay transition and finishes over the glass Sundial Bridge at Turtle Bay. Parts of the trail were affected by the Carr Fire of 2018 and the organizer is proceeding with course recertification.
