Spirit of Syllamo is a non-stop ultramarathon journey, covering the picturesque & challenging terrain located within the Sylamore Ranger District of the Ozark National Forest. The race course utilizes the Syllamo Mountain Bike Trails for the first 35M Loop and then traverses the entire Sylamore Trail & Extension, along with parts of the Ozark Highlands Trail for the 100M.
The 100 mile distance alternates on even and odd years. Between the two races, nearly every trail in the Sylamore Ranger District.
The 35m has 9,200ft of elevation change and is nearly 100% singletrack.
The Even Year 100m is 107 miles long with 33,000ft of elevation change.
The Odd Year 100m is 99 miles long with 30,000ft of elevation change.
Both 100m courses are 90% singletrack and 10% Forest Service Road.
All distances require the runner to be self-sufficient with gear and nutrition strategy. Aid stations are far apart and course marking is limited to turns.
