The Yamacraw 20K is a point-to-point trail race that begins at the Lick Creek Trail in Daniel Boone National Forest and ends at the Blue Heron Mining Community in Big South Fork National River & Recreation Area. The course shares approximately 7 miles with the Yamacraw 50k course. The 20K starts out quickly as runners race downhill towards the Big South Fork Cumberland River as it crisscrosses over Lick Creek multiple times. Along the way runners will be treated to magnificent singletrack trails and scenic landmarks that include stunning rock overhangs and waterfalls. Runners will cross Rock Creek, “A Kentucky Wild River”, some years by rope and other years by raft and cross the Grassy Fork Creek nearly a dozen times before climbing out to the second aid station. Then runners drop back into the woods on single track for 4.3 miles to Blue Heron for an iconic finish crossing over the river on a 100 foot high pedestrian bridge.

Course Markings:

The 20K will be marked with BLUE FLAGGING. Markings will be spaced maximum every .2 mile with more heavily markings at any turn or crossing trail. The race organizers will do everything they can to have the course marked well for race participants the day of the event. During the on trail sections of the course, runners must stay on the trail. No switchback cutting!

Just a final note, while the course will be marked, these trails will still remain open to the public. Please be courteous to all park visitors.
