Sylvan Grove, KS
All runs will take place on the Switchgrass Mountain Bike Trail at Wilson State Park. We are very excited to give you the opportunity to run on this amazing trail. The trail is easy to follow rugged single track with very few trees/wooded areas. We believe this will be a fantastic additoin to the other amazing ultra-events already being put on in KS. Beautiful views of Wilson State Park and Wilson Lake are plentiful.
The races will consist of 20(ish) mile loops – one loop for 20 milers, three loops for 100k runners, and 5 loops for 100 milers. Switchgrass is purely single track so we will likely start the runners about ½ from the trailhead to give everyone a chance to spread out. After that it is 100% trail-running.
