Course Overviews:

After a one-mile out-and-back on Shasta Dam, the Trail Marathon will follow dirt single-track trails down the Upper Sacramento Ditch trail, the Hornbeck Trail, and the FB trail before joining the paved River trail for the last 5 miles to the finish, 0.25 miles past the SunDial Bridge.  The Marathon course is mostly flat or gently rolling with a net elevation loss of 800′.



The 15K course (also the first 9 miles of the 55K) goes across the dam to Coram Road and quickly right on Road 1 and then climbs the big steep hill up trail 18 to great views of Shasta Lake and beyond before dropping back down to Road 1 and downhill for a mile to the Dry Creek trail and back along the lakeshore on Dry Creek to the dam, gently rolling with a biggish hill near the end (when you get to the top of the last hill you will see the finish line, below you and one mile away).  Cut-off time: 2 hours and 30 minutes (8:30 – 11:00).
