The Redding Marathon will begin at the Shasta Dam Visitor's Center parking lot. Participants will run directly onto the road that crosses Shasta Dam. Once they have crossed the Dam there is a paved road that descends for 1.75 miles where they  will access the paved Rail Trail. Run on the Rail Trail for the next 10 miles with the Sacramento River on your left with the first 7 miles being relatively flat and fast. They will come to the first aid station at 3.75 miles. Just after the aid station, run through an old 1923 railroad tunnel and then continue down stream on the flat Rail Trail to the Keswick Boat Launch.

Continue traversing the paved Rail Trail across Spring Creek Dam where you will be directed to make a sharp left onto the "Rail Trail Extension", This series of rolling hills will break up the flatness of the course. From there, a long downhill section awaits you as you pass the halfway point.  The Rail Trail extension ends at the Keswick Dam Road crossing.

Running past the pedestrian Ribbon Bridge you will continue downstream to the Middle Creek paved trail. Middle Creek trail has a gradual climb of 100 feet per mile. You will run this for a little over a mile where a course monitor will turn you around. Upon exiting Middle Creek trail, you will continue running downstream to the Diestelhorst Bridge. 

Runners will be run across and back on this newly renovated "historic" bridge and head upstream. Now the river will be on your right! You will sweep across the beautiful Ribbon Bridge,now on the north side of the Sacramento River Trail, you will make your way to the Finish Line at the Sundial Bridge.
